Bug Description
my laptop won't suspend, and it seems this is caused by a USB device with the 8087:0020 failing to freeze. this is what I get in dmesg around suspension time:
[ 141.789394] Suspending console(s) (use no_console_suspend to debug)
[ 141.919956] pm_op(): usb_dev_
[ 141.919958] PM: Device usb2 failed to freeze: error -2
[ 142.176574] PM: restore of devices complete after 5.323 msecs
[ 142.176743] Restarting tasks ... done.
[ 142.177478] PM: Basic memory bitmaps freed
please see the complete dmesg attached
