ya thats right, there are other modules usbcore ohci_hcd etc. but when i do a modprobe with the usbserial module with the product and vendor id, then only the /dev/ttyUSB0 device files are being created which i use in the dial program. even the cdc-acm module is not working in this case. it is not recognizing the module as an ACM device. Maybe the manufacurer does not have ACM support for this. I am still facing a problem though. when i disconnect the connection frm the dial program , the modem does not hang up. so i cant redial without rebooting OS. I tried removing the modules and killing pppd etc, but still that does not work out.. regards, Umesh On Sat, Mar 1, 2008 at 8:12 AM, Marvin Stodolsky <marvin.stodolsky@xxxxxxxxx> wrote: > Just for clarification, > usbserial just provides access through the USB ports cable to older > serial port supported hardware. > > But the serial drivers already compiled into the kernel are doing the > detailed work.
