This returns "true" ? dev.is_kernel_driver_active() Date: Fri, 8 Apr 2016 10:42:07 +1000 From: mrsh...@gmail.com To: pyusb-users@lists.sourceforge.net Subject: [pyusb-users] "Resource Busy" error message.
Hi All, First time poster here from Brisbane Australia :)I have only just started with using pyusb, so any advice would be greatly appreciated. My system - 64bit Arch Linux. I'm attempting to send commands to a Kuando Busylight (http://www.plenom.com/), using the example code here - https://github.com/walac/pyusb/blob/master/docs/tutorial.rst. At this stage all I have changed in the source code is the vendor and product ids to match the Busylight. The device is being found without problems using Vendor and Product IDs:"dev = usb.core.find(idVendor=0x04d8, idProduct=0xf848)" The next line "dev.set_configuration()" is raising a USBError. Result is the same in Python 2.7: Traceback (most recent call last): File "./busylight.py", line 19, in <module> dev.set_configuration() File "/usr/lib/python2.7/site-packages/usb/core.py", line 799, in set_configuration self._ctx.managed_set_configuration(self, configuration) File "/usr/lib/python2.7/site-packages/usb/core.py", line 128, in managed_set_configuration self.backend.set_configuration(self.handle, cfg.bConfigurationValue) File "/usr/lib/python2.7/site-packages/usb/backend/libusb1.py", line 730, in set_configuration _check(self.lib.libusb_set_configuration(dev_handle.handle, config_value)) File "/usr/lib/python2.7/site-packages/usb/backend/libusb1.py", line 552, in _check raise USBError(_strerror(ret), ret, _libusb_errno[ret]) usb.core.USBError: [Errno 16] Resource busy And also in Python 3.5: Traceback (most recent call last): File "./busylight.py", line 19, in <module> dev.set_configuration() File "/usr/lib/python3.5/site-packages/usb/core.py", line 799, in set_configuration self._ctx.managed_set_configuration(self, configuration) File "/usr/lib/python3.5/site-packages/usb/core.py", line 128, in managed_set_configuration self.backend.set_configuration(self.handle, cfg.bConfigurationValue) File "/usr/lib/python3.5/site-packages/usb/backend/libusb1.py", line 730, in set_configuration _check(self.lib.libusb_set_configuration(dev_handle.handle, config_value)) File "/usr/lib/python3.5/site-packages/usb/backend/libusb1.py", line 552, in _check raise USBError(_strerror(ret), ret, _libusb_errno[ret]) usb.core.USBError: [Errno 16] Resource busy Thanks in advance.
