Hi I cannot get any connected devices (except a libusb device) to reply to usb.core.find()
If I use a known device like usb.core.find(idVendor=0x1679, idProduct=0x2001) # Beagle usb.core.find(idVendor=0x0878, idProduct=0x1101) # Systec CAN usb.core.find(idVendor=0x0123, idProduct=0x4567) usb.core.find(find_all=True, bDeviceClass=0x02) # PCDC demo I just get empty lists. Like when I run above I get: __main__ start usb.core.find(find_all=True) No handlers could be found for logger "usb.backend.libusb10" [] usb.core.find(idVendor=0x1679, idProduct=0x2001) None usb.core.find(idVendor=0x0878, idProduct=0x1101) None usb.core.find(idVendor=0x0123, idProduct=0x4567) [] usb.core.find(bDeviceClass=0x02) [] usb.core.find(idVendor=0x0, idProduct=0x0) [] As you can see; just empty lists '[]' or 'None'. The devices are connected to the PC, because I can see them in the Windows XP Device Mgr. What is the "No handlers could be found for logger "usb.backend.libusb10" In the output above? Thankful for any help! Regards, Carl Stenquist Applications Engineering (919) 794 3477 Renesas Electronics America inc. http://www.renesas.com
