Hello,
I have a device not listed in "usb.ids":

First, just in case, does anyone know of succesfully using this device
with Linux ?
It has bulks in and out so i could load usbserial with vendor and
product options... however, i couldn't do much more, as it doesn't use
AT like commands, like with the serial interface.
In syslog i have this message:
---8<-----------
Aug 11 10:03:37 XxX kernel: drivers/usb/serial/usb-serial.c: the device
claims to support interrupt in transfers, but read_int_callback is not
defined
---8<-----------
Should this be implemented in a custom driver (anyway, i'm not really
sure this interrupt endpoint is used) ?
I took traces with usbsnoop: it seems the phone needs to know how much
data will be sent to it, before sending something to the bulk / a
"command"
Usb sniff shows that a "URB_VENDOR_FUNCTION_DEVICE" is present before
each "URB_FUNCTION_BULK".
How do I copy this behaviour , using "usb_control_msg" ?
Should a module be written, or can i use libusb to control this device ?
Thanks in advance,
Best regards,
Guillaume B.
