Hans, Thank you, that allows it to attach and the device nodes appear in /dev/ However I then can not seem to send any AT commands and get a response via either cu -l /dev/ttyU1 or cu -l /dev/ttyU1. Any further steps? Is there a way to virtually share this hardware with you? -Alfred On 11/12/15 12:31 AM, Hans Petter Selasky wrote: > On 11/11/15 20:51, Alfred Perlstein wrote: >> > > Hi, > > The device is very special in that it uses an interrupt type of > endpoint for receiving the data. > >> >> Endpoint 1 >> bLength = 0x0007 >> bDescriptorType = 0x0005 >> bEndpointAddress = 0x0084 <IN> >> bmAttributes = 0x0003 <INTERRUPT> >> wMaxPacketSize = 0x003f >> bInterval = 0x0002 >> bRefresh = 0x0000 >> bSynchAddress = 0x0000 >> > > In umodem.c you might want to change the USB matching filter to accept > interrupt endpoints: > >> [UMODEM_BULK_RD] = { >> .type = UE_BULK, // change this to UE_BULK_INTR >> .endpoint = UE_ADDR_ANY, >> .direction = UE_DIR_RX, > > This change will break other modem drivers, but at least it will give > some clues if it works or not. > > --HPS >
