Is there a way to force the RNDIS driver to bind to this? If that fails, I can try doing some troubleshooting on my own. Make of the device may be before RNDIS was "standardized" so I'm not sure what to expect. # lsusb -d 0894:0010 -vv Bus 001 Device 022: ID 0894:0010 TSI Incorporated Remote NDIS Network Device Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 2 Communications bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 16 idVendor 0x0894 TSI Incorporated idProduct 0x0010 Remote NDIS Network Device bcdDevice 0.00 iManufacturer 1 TSI Inc. iProduct 2 NDIS Device iSerial 3 00004855 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x003e bNumInterfaces 2 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xc0 Self Powered MaxPower 2mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 2 Communications bInterfaceSubClass 2 Abstract (modem) bInterfaceProtocol 255 Vendor Specific (MSFT RNDIS?) iInterface 0 CDC Call Management: bmCapabilities 0x00 bDataInterface 1 CDC ACM: bmCapabilities 0x00 INVALID CDC (ACM): 05 24 02 00 01 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 1 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 10 CDC Data bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x03 EP 3 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 can't get device qualifier: Resource temporarily unavailable can't get debug descriptor: Resource temporarily unavailable Device Status: 0x0001 Self Powered
