I am using Dlink DWP-157 3G usb modem to work on Jetson TK1. The modem normally works with Ubuntu 14 or 16 but not working on Jetson. Running
lsusb
detects the USB device, but not mounts as a cd-rom. However, Disks program shows the device as cd-rom but could not eject.
The device came with x86/64 drivers which is installed but not working. I have used r21.5 and Grinch 21.3.4 but no luck. Connecting the device over USB shows
sg0
file but no
sr
files.
How can I enable the modem to work?
The title says it is a modem, but the sg0/sr implies mass storage. Some USB devices (in fact many more than people realize) are actually multiple devices using a single USB cable. If this were a modem, then it would be entirely a serial device without mass storage. Can you give more information on the specific model? Also, notice that when you see the device under “lsusb” there will be an “ID” column. The column will be something like “0955:7721” (which is what a recovery mode TK1 shows). If you look at the ID then you can limit lsusb to just that device via “lsusb -d 0955:7721” (adjust for your ID). Would you please paste the full verbose output here of:
sudo lsusb -d 0955:7721 -vvv
(the forum icon in the upper right while posting has a “code” </> icon…paste the log into the middle of this after clicking on it)
In addition, check the last message in dmesg prior to inserting the USB cable. Then insert the USB cable and post the additional output after that line from dmesg.
The board detects it properly but not mounting as a proper media device.

dmesg log also catches the event in normal ways when disconnected and conected again. What device type tegra should mount it ?

One thing is clear from the lsusb…this is a composite device which looks like a single device, but it may have multiple drivers involved. The bulk transfer for data does act like a hard drive, but it may not be useful in every way a regular USB mass storage device is. Other functions for control of the device definitely need different drivers.
This in particular seems to be an issue:
iInterface 3 COM(comm_if)
** UNRECOGNIZED: 05 24 00 10 01
** UNRECOGNIZED: 04 24 02 0f
** UNRECOGNIZED: 05 24 06 02 03
** UNRECOGNIZED: 05 24 01 03 03
Perhaps this device requires firmware…I don’t know. Perhaps this interface simply needs a custom driver specific to the hardware. It may be a case of researching the particular device and finding out which drivers it uses, and also whether or not firmware is required.
You may want to experiment with:
sudo mount -o loop /dev/sg1 /mnt
…and if that works:
ls /mnt
sudo umount /mnt
