USB connections

Is there a limit to how many USB redirection connections there can be on the View Desktop? So can I have a scanner, printer, cell phone, etc etc?

Thanks.

I really don't know if there is a limit - I already saw a 4 usb device desktop running. I think this limit should exist, but if you will use, like, 3 or 4 devices I don't think it will be a problem.

Just take some care with PCoIP on View 4 that are having some issues with USB connections.

Hi,

Please see the following quote from the VMware View Manager pdf

"View Extended USB Device Redirection

View allows the redirection of a variety of locally attached USB devices for software

that run on a user’s virtual desktop. Suitable devices, when attached, can be selected

from a dynamic drop‐down menu in View Client. Devices attached after the virtual

desktop session starts will appear in the menu and are available for redirection after

being initialized.

Some devices, such as printers, local USB flash drives, and smart cards, can be

forwarded to the virtual desktop using standard Microsoft Remote Desktop Protocol

(RDP). But View Client USB redirection extends the range of usable devices and the

functionality of some devices beyond that provided by RDP. For example, sound can be

brought to the local machine using RDP, but disabling this feature and using View USB

redirection allows you to use VoIP devices.

View USB redirection is initiated after the user is authenticated. Because of this, smart

card forwarding is limited to RDP functionality so that smart cards can be used to

authenticate the virtual desktop session. As a result, these devices do not appear in the

View Client devices menu. Human interface devices (HIDs), such as a keyboard or a

mouse, are also filtered from the USB device list because these devices are required

locally and function without being forwarded or redirected.

RDP forwarding and View USB redirection can be governed through Active Directory

Group Policy and View Administrator. Using View USB redirection requires View

Client, View Agent, and the user to have administration rights on the View Client and

the View Agent operating systems."

There is no limit's set in this description and I have not seen any information on limitations of redirection during deployments as yet.
