I am having problems getting the later Option GTM378, 380 and 382 3g
modems to work properly with the u3g driver on FreeBSD. Older
generation 378s work just fine, but I can crazy slow speeds when
using the newer ones. (21kbps vs about 1.5Mb based on the signal here
at the office)
On an older generation 378, all I did was add the device ID and all
works just fine
Not sure if it makes a difference, but the connect speed on the
"working" 378 shows
Jan 1 08:38:33 alix ppp[1758]: tun10: Chat: Received: CONNECT 3600000
vs
Oct 2 10:11:37 378n ppp[1085]: tun10: Chat: Received: CONNECT 7200000
How do I find out what the "right" speed is and set it for the device ?
Despite the higher connect speed, I get a transfer rate of about
21Kbps. On the older gen modem, I get 1,376Kbps
also, on the newer 378s I need to do a mode switch for it to
work. On RELENG_7, I made the following changes based on what was in
usb_modeswitch
