so that regkey still exists on my laptop... i guess that isn't absolute proof its still being honored, ) unf i cant check the code right now. should be quick to test though. maybe you can post back when you know... cheers p

Hey Eric Do I still score the community points then having written the blog that helps? Tbh, I need to check if that config value is still available. Can I ask what is are your client devices? Cheers Peterb

hi Eric not sure what happened to that feature, but at least I'm still here - don't worry!  - sorry, but serial port redirection (and scanner redirection) is only supported with Windows clients today and only in windows guests (ie not supported in the Horizon for Linux desktops). I don't have any knowledge of if or even when it will be coming to other platforms. cheers peterB

I've just seen your posts. Sorry to hear that you are having significant difficulties. I will try and help get the right people looking at this. You mention vmware support; as such, I presume you have filed one or more Support Tickers (SR's?) If so, could you post back with the SR numbers here? this will help me get up to speed and try and identify what is going on, cheers peterB

So we recently added Serial Port Redirection - you will need Windows Clients v3.4 or later and Horizon View 6.1.1 or later. Earlier builds don't support explicit serial port redirection. I have tested with many pin pads etc and they do work. But, we haven't been able to test with a lot of banking software as it is often proprietary or requires the banks mainframes to work - so, whilst I would expect it to work, it's not necessarily been tested and so I can't say for certain. If there are issues though,we would want to investigate because it should work... just make sure you don't forward the devices using usb redirection, and use the com port redirection feature instead, cheers peterB

hi david, i will redirect these comments to the relevant teams in vmware. is the problem here that you are needing to use something called nested sessions? ie, you remote in to say a win7 vdi desktop, and from there you launch a view client to give you the app remoting functionality? ie you need to do a double hop of the usb into win7 and then on into 2012r2 app or desktop session? or are you trying to go direct into 2012? i will make sure the relevant folks see this, and they can look into whats being asked for here, (fyi; I dont work on USB redirection anymore) cheers peterB

just a quick note to say that the Microsoft fax/scan app now works as a scanning app with Scanner Redirection with the newly released Horizon 6.1.1 agent (and the Windows 3.4 client). cheers peterB

no, we dont "certify" hardware as that would be a never ending task for us! what is the problem you see - do you just see a grey screen? are you sure the webcam drivers are correctly installed? can you try using our RTAV Test tool and try that on the client end point to see if pictures are seen? if you use that app on the guest, then do you see grey screen? see: Real-Time Audio-Video Test Application – VMware Labs cheers peterB

white paper now updated to reflect the fact that usb storage devices are supported on rdsh2012 http://www.vmware.com/files/pdf/techpaper/vmware-horizon-view-usb-device-redirection.pdf cheers peterB

do you see usb devices appear in the usb menu?  , or does the menu bar show "usb not available" (or some other similar comment) on the thin client, is any other vdi client software installed - we have sometimes see conflicts between various vendors clients and their usb redirection.

well, i wonder if the problem is related to microsoft changes that may have been pushed to the win8 client (or the desktop) around SSLv3 and the poodle patch.  KB2992611 im totally guessing here, and really next steps would be to look at logs. but if it was the poodle issue, then the approach would be to either not install the KB as above (which isn't really recommended from a security perspective) or better to upgrade the agent to 5.3.4. but, if you don't want/can't do either right now, then we would need to see debug logs from client and agent to understand the exact failure. (the solution might still be the same, but at least you would know for sure.) for reference, we did see a similar "wierd" connection issue that worked from some clients and not others, and that turned out to be the above issue. see Re: USB redirection not working, port 32111 connection refused cheers peterB

looping back on this thread, and having worked offline on this, looks like we found the cause. with View 5.3.4 because of poodle security vulnerability, SSLv3 is disabled by default after Microsoft patch KB2992611 is installed. SSLv3 is enabled by default for older version till 5.3.3. The issue happens here because the new clients don't support SSLv3 yet the older agents do, and once the Microsoft patch is installed ultimately an agreement on the authentication cant be reached, and the USB channel doesn't open. The correct security advisory here is for customers to update the agents to 5.3.4. or, you could uninstall the Microsoft patch but that's not recommended.

can you confirm what specific agent version you have installed? I suspect you may need to upgrade to 5.3.4 to pick up the latest security fixes (for poodle), which may cause usb authentication to stop working if you have picked up the microsoft security updates. this is a total guess, based on not looking at logs, so I might be incorrect. but can you start by confirming the agent version and we can go from there? cheers peterB

zero clients do not support RTAV. thin clients typically do, but that is dependent on the firmware from the thin client vendor. If they are running a view client > v2.2 then they typically should support. cheers peterB

hello a few more questions.... but, I think it should work.... What version of the View Agent are you connecting to, and can you confirm that RTAV is installed in it? As per Real-Time Audio-Video (RTAV) For Horizon View, Part 2 | VMware End-User Computing Blog - VMware Blogs the linux client supported RTAV from version 2.2 onwards. TBH, I cant say for sure if HP does any adjustment of the package when they install on the thinclient (I dont work on the client team), but I dont think they do. From your description of device manager, it sounds like the Webcam is being redirected via USB redirection , since when being redirected by RTAV the real device would not appear in device manager - only the "virtual webcam". As such, a couple of things to check; 1. do you have access to the thin client file system? if so, can you check that the following file is present:       /usr/lib/pcoip/vchan_plugins/libmmredir_plugin.so 2. if so, then rtav should be installed in the client. So next up (and this is something i thought we did by default in the linux client, but maybe its been adjusted in the HP install) is that Video devices should be blocked by default for USB redirection. This can be done either on the client device, or probably better (for roll out purposes) in the view agent via gpo... client config in the file:   /etc/vmware/config     (create it if it doesnt exist), add the following lines;     viewusb.AllowAudioIn="False"     viewusb.AllowVideo="False" OR: agent side config; using the usb agent configuration file set the following gpo:    ExcludeDeviceFamily o:video;audio      (o: means override any config set on client side, and means its an agent side setting). (see http://www.vmware.com/files/pdf/techpaper/vmware-horizon-view-usb-device-redirection.pdf for more details on usb configuration) let me know how you get on, cheers peterB

can you confirm what version of the View Client you are running - is that 2.3.4? also, can you confirm you are connecting using PCoIP? please ensure that the webcam is not being redirected via USB redirection. (does it appear in the windows guest as a usb imaging device? cheers peterB

cool, yeah - thats a good place to start. typically its used for webcam type use cases, but i do know of customers using it to grab images from cameras etc like your use case. (eg for things like reception kiosks to grab photos for security passes or doctor patient records etc) cheers peterB
