Please refer to the following thread I post to Linux-USB-User list. I've
seen similar problem with PICkit 2 when hotplugging.

According to Alan Stern (one of the active Linux USB developer), it is
possible due to lousy cable or firmware bug or an old Linux kernel.
From Alan
"110 is ETIMEDOUT; see include/asm-generic/errno.h. In
Documentation/usb/error-codes.txt it says that -ETIMEDOUT indicates
either the device failed to respond to a request or a timeout expired
before a transfer was completed."
