usb: Samsung Portable SSD T5 inaccessible in Sculpt Linux VM (SuperSpeedPlus device) #4598

Closed chelmuth closed 6 months ago

chelmuth commented 2 years ago

The device 04e8:61f5 seems to be initialized correctly when plugged except the following string descriptor errors in the host driver.

[init -> drivers -> usb_drv] Could not read string descriptor index: 0
[init -> drivers -> usb_drv] Could not read string descriptor index: 0
[init -> drivers -> usb_drv] Could not read string descriptor index: 0

The USB storage driver successfully reads the first blocks of the device and, thus, the partition table is parsed correctly. Subsequent usage in Inspect and e2fsck also worked.

Further, if the device is passed to a Linux VM in VirtualBox, the guest fails to initialize the device. This stems from the fact, that the device is USB_SPEED_SUPER_PLUS, which is currently not supported in the USB session and qemu-usb as well. Clamping the speed to USB_SPEED_SUPER in repos/dde_linux/src/lib/lx_emul/usb.c did not suffice to make it work but resulted in other errors.

Based on the findings in #5041, the following lines in the Linux log look suspicious and hint UAS may be the cause of this issue too.

Let's close this issue as duplicate of the more generic "usb: USB passthrough breaks UAS #5041".
