Having trouble connecting Basler acA1920-155uc USB3 high-speed camera to CentOS 7

[sclassen]

Hello,

When I plug in my Basler acA1920-155uc USB3 high-speed camera and it connects to CentOS 7 I get the following warning from VMWare Fusion:

Within CentOS I see this message is /var/log/messages:

Feb 22 11:04:15 localhost kernel: usb 1-2: new high-speed USB device number 11 using ehci-pci

Feb 22 11:04:15 localhost kernel: usb 1-2: device descriptor read/64, error 18

Feb 22 11:04:16 localhost kernel: usb usb1-port2: unable to enumerate USB device

Any idea how I might remedy this issue?

Thanks,

The CentOS log shows "ehci" which suggests it was connected using USB 2.0 instead of USB 3.0 while the camera is a USB 3.0 device. USB 3.0 should show "xhci".

Have you tried setting the USB controller in the CentOS VM to be USB 3.0?

If setting the USB Controller to USB 3.0 still gives problems, you could try the quirks as outlined in this KB.

Yep. That did the trick. I guess I should spend a bit of time familiarizing my self with all the advanced options in the VM settings pane.

I switched from USB 2.0 to USB 3.0 and now the camera works.

Cheers
