Hello...
Attached is simple example. The problem is that it's works in linux but
not in windows. And I wan't to be portable. Can someone tell me what I
do wrong?
seems that <class 'usb.core.Device'> is handeled different in win (it
return long string?!)
#there is current only one device with correct vid/pid attached
import usb
def openUsb(vid,pid,name=''):
try:
devices = usb.core.find(idVendor=vid, idProduct=pid, find_all=True)
for dev in devices:
print type (dev)
print dev
if (usb.util.get_string(dev,256,2)==name):
dev.set_configuration()
return dev
except Exception as e:
print e
USBdev=openUsb(0x16d0,0x06ad,'Q_ANALISER')
if not USBdev:
print "Device not found"
exit(0)
print "Device found ",USBdev
'''
