Cause

Previously replaced robot is defective. Error is seen after robot replacement.

Bug 24704615: USB: LUN Communication Timeout during cartridge move test"

@ Planned Hardware Fixes to prevent most USB communication faults (EMI
@ like)that cause this and other type of behavior will be implemented in these
@ two EC's adding to the Robot two changes:
@ Anodized Leveler and KLX film cover
@ Component EC: E0027982
@ Incorporation to Assy EC: E0033772

Solution

For these 2 EC's, the only robot that has these 2 ECs implemented is part number 7332809 which is the new long robot for the SL150e.

The higher P/N 7333965 robot actually does not have the EC implemented because it was released before the long robot was released.

If you have a USB HUB reset then the 7332809 would be the only recommended robot at this time.

In the next month or two they are going to be releasing a new robot P/N that will contain 2 more ECs that are meant to help with the USB HUB reset issues.
