Thanks I'll check this out! 1. Is this mentioned in documentation? Sorry I missed it.
2. When I go to http://www.libusb.org/wiki/windows_backend I get "504 Gateway Time-out nginx/0.8.42" I tried two different networks. Is this old? Regards, Carl =================================== It feels like you didn't install your devices with WinUSB. Please, check libusb 1.0 windows backend docs for details: http://www.libusb.org/wiki/windows_backend -- Best Regards, Wander Lairson Costa From: Stenquist, Carl Sent: Tuesday, August 16, 2011 11:45 AM To: 'pyusb-users@lists.sourceforge.net' Subject: usb.core.find() 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
