First insertion.

Does the device actually have manufacturer 1, product 2, serial number 3?
What do you get with "lsusb -v" with it plugged in to an unaffected system?
How about on an affected system?

I assume you had plugged the same device in back into the same port?

This is -ETIME.  First time, the EHCI (USB 2.0) driver claimed the
device, but this time OHCI makes a try.

Does the misbehavior happen for arbitrary USB devices, or just this
one thumb drive?  (E.g., if you have any old USB 1.0 devices, can you
reproduce this with it?)

Was this a regression?  (I.e., if you know of any older kernel version that
is not affected, that would be useful.)

EHCI driver gets a little further but does not succeed either.

Now the device detection goes crazy.

This is -ETIMEDOUT.
