http://ubuntuforums.org – Dear all, I have a problem to connect the usbnet device on PXA310 blob. It's hard for ubuntu to detect it. ubuntu can detect this device 1 time, if I plug it to PC 20 times. But it can be detected everytime on WINXP. Below is the dmesg log, the lines in red indicates that ubuntu detected my device 1 time: [ 5794.650787] usb 5-3: new high speed USB device using ehci_hcd and address 3 [ 5795.133941] usb 5-3: new
