Stephane,
Some more changes:
- when filling input_id structure convert USB descriptors (le16_to_cpu)
- driver_info field in usb_acecad_id_table was not set up so all tablets
were set up as Flairs
- in last patch I goofed up "path" setting, fix that
Could you please try it once more, I promise it will be last time :)
Thank you!
