Hi I am experiencing a random problem when reading files from an USB stick: sometimes, the reading from USB stops, and when his happens I find the PE bit in the PORTSC1_H register of the USB reset to 0.
I am currently using lpcUSBlib, and when the problem arises, I have found no way to reset the USB back to work mode.
This happens in a repetitive manner with some USB stickd; the same files copied in a different USB stick would give no problem...
Is there any easy way to diagnose/reset the USB when the Port Enable bit resets to zero?
Any other hints?
