Wrong CSW status #124

Open MaartenStottelaar opened 6 years ago

MaartenStottelaar commented 6 years ago

Some USB devices seem to return an invalid CSW status, even when the operation apears to be correct. If I return TRUE in cases where csw.getbCswStatus== 1 in "transferCommand" (line 134) with these USB devices, the data transfer seems to be OK. For now I ignore csw.getbCswStatus== 1, but like to solve this problem.

Hey there,

and sorry for the late response.

Thanks for this information, I never had this problem, to be honest. Can you maybe elaborate a little which phone and pen drive you use? Is there a pattern?

MaartenStottelaar commented 6 years ago

Dear Magnusja,

I am running the code on a Enybox 'Android box' with Android 6 (I tried several pieces). It seems that about 50% of the USB sticks do not work, but I have at least one official Sandisk 32G that works fine. I also noticed that (smaller) FAT formatted devices do not work, but that can of course eailly be solved.

Hi!, i solved the problem, just need a delay before calling discover function and all usb sticks work.

RandallXia commented 6 years ago

Hi there! I sleep the thread 1 second before i call device.init(); and it works!

alVal6 commented 6 years ago

Nice!!! its great to hear it, you can try timer Countdown in order to avoid sleeping the thread

I'm still getting this. The 1 second sleep doesn't help.

alVal6 commented 5 years ago

Try with 3 seconds delay
