The only additional info I've been able to get is by running 'lsusb'. It lists the USB Flash drive that usbcore fails to probe correctly.
Here is the output from 'lsusb':
Bus 004 Device 004: ID 08ec:0010 M-Systems Flash Disk Pioneers DiskOnKey Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 03f0:1e11 Hewlett-Packard Bus 001 Device 002: ID 0409:0058 NEC Corp.

Same exact problem here.
I am able to use some USB Flash drives without issue, but some fail. The failures lock up the whole mount subsystem capability, and the only way to fix it is to restart. My errors are just like the below. Is there a way to gather detailed information for the failed devices?
