usb: USB passthrough breaks UAS #5041

Open atopia opened 8 months ago

atopia commented 8 months ago

Passing through a LaCi STLP2000400 external harddrive to a Linux VM in VirtualBox breaks the drive's UAS mode, the fallback usb-storage mode (MSC) works.

As a workaround, the fallback mode can be forced in the guest by creating /etc/modprobe.d/no-uas.conf with options usb-storage quirks=059f:1105:u.

On native Linux, switching from theusb-storage fallback to uas works on the device:

When passing the harddisk to a VM, UAS fails with the following error:

Forcing sculpt_manager to ignore the device as storage via 17e84def131 and thus preventing the prior use of the harddrive from Sculpt does not solve the problem.

The failing UAS mode might be connected to #4598.

Unfortunately, this issue is still valid with the renewed usb_host_drv on Sculpt 24.04.
