Hi!

I have been trying to use usb_mass without success. I have a Transcend 256MB JetFlash. I'm trying to test with mass_example.elf. It jams when trying to read directory listing. I added some XPRINTFs to the iop mass_stor.c and noticed that it jams when usb_bulk_status() is calling WaitSema(). I have tested with usbd.irx from a demo disc and npm-usbd.irx.

Output when executing mass_example.elf, debug messages turned on in usb_mass.irx:

Code:

# ps2client execee host:mass_example.elf

It jams here. If I'll remove the usb stick, it will (sometimes) continue:

Is there something that could be done? Or will I just buy another usb-stick for PS2? :)

I commented this line from mass_stor_warmup():

usb_bulk_manage_status(dev, -TAG_INQUIRY);

and from usb_bulk_manage_status():

usb_bulk_reset(dev, 1); /* Perform reset recovery */

Now it seems to work just fine. :) Maybe my stick is non-standard or the warmup sequence is incorrect? More error handling should be added.. Seems that UsbBulkTransfer() does not necessary ever call usb_callback() functions. Some timeout should be added?

I added fioDopen(), fioDclose(), fioDread() and fioGetStat() support to usb_mass. Here's the patch:

The warmup content is experimental, it is quite possible it will not work for all devices. You can try to find more reliable warmup sequence.

I've experienced lock-ups of the usb part when the debugging printf are used. When the printfs are removed then program works (most of the time :-) fine.

Thanks for the diff, I will update the sources soon.

I also had the lockup problem with my Transcend 128MB stick.

Looking forward to using usb_mass in one of my projects :)
