I have 2 Clips both set to MSC mode. One is version 01.01.32A and the other is 02.01.32A. Neither connect if I just plug them into the computer’s USB port. If I use this trick:
Turn off Clip
Put into HOLD
Press and hold center button
Plug into USB port on PC
The Clip with version 02.01.32A will be recognized. DMESG shows this:

I tried the same trick with the version 01.01.32A, but it doesn’t work. I get:
[3884.424035] usb 1-5: new high speed USB device using ehci_hcd and address 13
[3899.475096] hub 1-0:1.0: unable to enumerate USB device on port 5
What does that tell you?
