Hi all,
if I interpret the following line
--
#define IS_ISDN(sc) \
(le16_to_cpu(sc->usb_dev->descriptor.bcdDevice) & 0x80)
--
correctly, the annex a/b (pots/isdn) autodetection works be checking for the
0x80 bit in the USB revision number. This fails at least for the "Devolo
MicroLink ADSL Fun USB ADSL-Modem", which is sold as being German T-DSL
compatible (T-DSL is *always* annex b, irrespective of the telephone line
being pots/isdn) and has
--
Vendor=1039 ProdID=2110 Rev=40.02
--
and does work with isdn if the correct firmware is loaded into it.
The wiki suggests copying around the files in /lib/firmware/ueagle-atm which
does work but which is IMHO no clean solution. Neither for regular users
(should we really tell them they have to mess around with the firmware
images?) nor for distributors (they will probably refuse to introduce
configuration dialogs which will copy around firmware image files). Besides
that, copying around the firmware files is neither logical nor consistent:
The file names include 'p' for pots and 'i' for isdn, copying the files
around results in bogus file names.
Thus I'd suggest to introduce a new module parameter called "pots_isdn" with
the following possible values:
0 = auto (default)
1 = pots
2 = isdn
Modifying the IS_ISDN macro accordingly should be easy.
Comments, please?
Cheers, Johann
