I'm using Orange PI PC board, OrangePI_Jessie_Xfce.img with kernel
3.4.39. I have two modems that both work on Raspberry Pi with Raspbian:
TRENDnet TFM-561U and USRobotics USR5637
I'm try to get /dev/ttyACM0 so I can use the modem with my python
scripts.
I can't get either to work. Any help or suggestions would be greatly
appreciated. All the information I could gather below:
Only the USR modem will be seen via lsusb:

As with nearly all the other images I think you are missing the kernel-modules. Whoever made the image didn't bother compiling all the drivers because they didn't need them themselves and thought no one else would need them either. You could check from /proc/config.gz what modules it was compiled with.
This is the good guidelines specially for you to those people new at all to blogosphere, simple along with exact information… Cheers pertaining to expressing this. Absolutely essential go through content. sexy i love my boyfriend clothes
