FS#12714 - Sansa Fuze V1 USB Fails on daily build (ad46064-120710)
I upgraded my Sansa Fuze V1 (AMSV1) from the current stable release 3.11.2 to Daily build (ad46064-120710). With Rockbox powered on, any attempt to connect USB to my WinXP fails. The USB icon is displayed briefly, followed immediately by the white screen - Undefined Instruction at 0000003C. This is repeatable. Recovery is via a power down.
Note: the USB connection works fine with the current stable release 3.11.2 and this is the first daily build I have tried,

AFAICT this has been long resolved, by
bumping the USB stack size a smidge.

I’ve seen the same symptom (undefined instruction, 0000003C) on my sansa clip zip (which is an AMSv2 player), although I think it didn’t happen immediately.
Theres a lot more information about this bug report here: http://anythingbutipod.com/forum/showpost.php?p=616375&postcount=9
Sounds like a general stability problem with various builds on the Fuze v1, so I suspect its the same problem as
FS#12184.Today I did a clean install of Daily Build (ad46064-1207-10) on my Sansa Fuzev1, by removing the existing .rockbox folder and then installing the daily build as a “clean install”.
I restored my config and sound settings, installed the 3.11.2 font package and the kissv2 theme that I was using before and I now cannot duplicate the usb problem
FS#12714.The usb function on my Sansa Fuzev1 with daily build (ad46064-120710) now works correctly, after this “Clean Install :)
Previously I connected the Fuze usb to a 4 port hub and when I noticed some random usb disconnect and then quick reconnects during a usb session, I removed the 4 port usb hub and plugged the Fuze into a dedicated PC USB hub. The “clean install " today used the dedicated PC USB port, whereas the 4 port hub was used when I reported
FS#12714and I suspect the 4 port hub caused some file corruption that affected the USB function.Perhaps the Rockbox manual should recommend a direct PC USB connection, not a 4 port hub?
Based on this “clean install” result, I think you can close this report.

I can reproduce this with the screendump feature. I can also manage to avoid it by increasing the USB stack size. So something seems to be heavy on the usb thread stack (not screendump) causing this during normal operation
