ST32F205 USB host error when reading from flash memory stick

Question asked by hargreaves.steve on May 9, 2013
I am observing an error when ST32F205 is reading from a flash memory stick.

The scenario is:
Using ST USB OTG drivers V2.1.0 (in host, FS mode)
The file being read is approx 300KBytes.
The failure occurs at random points through the read, and the exact symptoms vary.
Seems to be a timing issue as doing lots of debug printouts allow the USB read to complete ok.

Can anyone:
1) Confirm that the ST USB drivers should be capable of handling this reliably ?
2) Throw any light as to where the problem might be arising ?
3) Point me towards any guidance notes on how the ST USB drivers should be ported onto my hardware ?
