Hi all, Can anybody recommend a 4G USB dongle that works with OpenBSD, ideally without any kernel fiddling (although I am open to this if necessary)?
The umsm(4) manpage claims to support the Huawei E3372, but the reality with this model is complicated. I have a pair of E3372h-153 dongles, one with its original Hi-link firmware, one reflashed to stick firmware. With Hi-link firmware, I get a USB serial port that I can issue AT commands on, but when I say "ATD*99#", it says "CONNECT" and then nothing happens. I'm pretty sure that this is because Hi-link firmware does not support PPP mode at all. With stick firmware, the device is not supported at all. On a different OS, I get two serial ports and a CDC NCM device, and I can connect by issuing an AT^NDISDUP command on one of the serial ports, and DHCP-ing on the NCM interface. Support for this mode can perhaps be easily added to umsm(4), but OpenBSD lacks support for CDC NCM, and umsm(4) support wouldn't be much use without that. Does anyone have experience with the E3372 on OpenBSD and has managed to make it work, at least in some mode? Or is there another dongle that "just works" with OpenBSD? Many thanks, Alex
