FS#12638 - AMSv2 USB hangup

SanDisk Sansa Fuze2 (AMSv2) hangs up randomly being connected to PC USB port. There is an “Undefined instruction at 34EA0008” message appears on blank screen. It more often happens on the second re-attach of a device, after safe USB disconnect when I attach it again.

Tested on Ubuntu and WIndows 7, with several PCs, with USB 1.1 and 2.0. The same situation. What might cause this problem?

Closing bug reports for the old USB stack now that we have the new one committed and stable. Most likely these problems are fixed now.

I’ve seen this happen occasionally after disconnecting the player. It’ll either crash after disconnect, or else crash if quickly reconnected. I suspect that under some circumstances things are not reinitialized correctly after leaving MSC mode.

I have this problem with the crash on disconnect too. Happens every time. Many more problems with the Fuze V2 in particular that are not applicable on the V1.

Same issue on the v1

Any news on this? (I would not want to seem bothersome, but this bug is really annoying.)

Hope this helps:
Very often on connect i get:
“undefined instruction 0000003C” If if it doesn’t happen on connect, i _always_ get it on disconnect (same error).
Sansa FuzeV2.
