All:
I was fiddling around with something this weekend and wanted to make sure it
was valuable before I finished it off.
I've been working to auto-generate Python code to do USB class lookups based on
the info stored at:
http://www.linux-usb.org/usb.ids
Basically it reads the info in that URL and generates code like:
# USB library
# Generated on: 2011-08-31 00:16:39.468550
def dev_class_to_string(dev_class_id):
if dev_class_id == 0x0:
ret_val = '(Defined at Interface level)'
elif dev_class_id == 0x1:
ret_val = 'Audio'
elif dev_class_id == 0x2:
ret_val = 'Communications'
elif dev_class_id == 0x3:
ret_val = 'Human Interface Device'
elif dev_class_id == 0x5:
ret_val = 'Physical Interface Device'
elif dev_class_id == 0x6:
ret_val = 'Imaging'
elif dev_class_id == 0x7:
ret_val = 'Printer'
elif dev_class_id == 0x8:
ret_val = 'Mass Storage'
elif dev_class_id == 0x9:
ret_val = 'Hub'
elif dev_class_id == 0xa:
ret_val = 'CDC Data'
elif dev_class_id == 0xb:
ret_val = 'Chip/SmartCard'
elif dev_class_id == 0xd:
ret_val = 'Content Security'
elif dev_class_id == 0xe:
ret_val = 'Video'
elif dev_class_id == 0x58:
ret_val = 'Xbox'
elif dev_class_id == 0xdc:
ret_val = 'Diagnostic'
elif dev_class_id == 0xe0:
ret_val = 'Wireless'
elif dev_class_id == 0xef:
ret_val = 'Miscellaneous Device'
elif dev_class_id == 0xfe:
ret_val = 'Application Specific Interface'
elif dev_class_id == 0xff:
ret_val = 'Vendor Specific Class'
else:
ret_val = 'UNDEFINED'
return(ret_val)
This would need to get cleaned up and better integrated with the overall libusb
library, but before I went any farther I wanted to check and see if this was
functionality that was:
-interesting
-desirable
-etc
There is a bunch of other info at http://www.linux-usb.org/usb.ids with vendor
and protocol info, etc and the stuff I've been putting together to include that
as well. Again - just wanted to see if this was interesting/useful before I
put in the time to make it more complete.
Thanks,
Dan
