FTDI serial USB converter under 32-bit kernel not working. Ftdi_sio version 1.6. kernel version >= 3 (gentoo-sources and vanilla-sources tested). Tested compiling module and into bzimage Tested with FT232RL single port chip and FT2232D dual port chip 64-bit tested and unaffected Reproducible: Always Steps to Reproduce: 1.Put FTDI adapter into usb 2.open serial port device 3.read bytes from device Actual Results: If some bytes were received byte return always one byte of value 0. Expected Results: Read all bytes received on serial port Attaching leds circuit over rx/tx insted of bright light I notice very weak lightin when trasmitting/receiving. With same hardware and 64-bit kernel leds activity is normal and all works fine.
don't CC on your own.
Tested gentoo-sources 2.6.32-r29 and unaffected both 32-bit 64-bit (I'm always using same hardware)
It's been awhile here. Is this still an issue with later kernels?
