Package: fwupd
Version: 1.9.14-1
Severity: important
Dear Maintainer,
I have a Kensington Expert Mouse (trackball) connected by USB. Today I
installed the update to fwupd 1.9.14 that `apt upgrade` offered me. Soon
afterwards, my trackball stopped working. I was able to re-enable it by
disconnecting and reconnecting it, but this proved short-lived - it eventually
cut out again. I reconnected it and it worked for a little longer, then I had
to reconnect it again, and eventually reconnecting it did nothing - it stayed
non-functional.
I started checking the logs, and eventually I noticed this error message
appearing shortly before the messages recording the trackball's reconnection:
fwupd[1106287]: 01:23:55.952 FuUsbDevice failed to load BOS descriptor
from USB device: USB error on device 047d:1020 : Operation timed out [-7]
I can confirm that 047d:1020 identifies my trackball:
$ for name in
/sys/bus/usb/devices/1-1.6/{idVendor,idProduct,manufacturer,product}; do printf
"%s\t%s" "$(basename "$name")"; cat "$name"; done
idVendor 047d
idProduct 1020
manufacturer Kensington
product Kensington Expert Mouse
I ran "systemctl stop fwupd", reconnected my trackball, and then it worked
fine.
Investigating further, I discovered that I can disable my trackball on-demand
by running "sudo fwupdtool get-devices". It prints the following output:
Loading… [******* ]05:01:05.132
FuUsbDevice failed to load BOS descriptor from USB device: USB error
on device 047d:1020 : Operation timed out [-7]
Loading… [************************************** ]
...and then my trackball stops working until I reconnect it.
It seems that fwupd 1.19.14's changelog mentions "Fix DS-20 descriptors by
opening the GUsbDevice earlier", and apparently "DS-20 descriptor" is a
specific kind of "BOS descriptor".
