https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263783 --- Comment #3 from email@example.com --- (In reply to Pierre Pronchery from comment #0) Thanks for publishing this! I was going to give it a try with a MC7700 modem, but the driver doesnt seem to attach. I put the device into MBIM mode (I think) AT!ENTERCND="A710" OK AT!UDPID=68A2 OK AT!RESET OK It comes back as ugen2.3: <Sierra Wireless, Incorporated MC7700> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (0mA) bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x0000 <Probed by interface class> bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x1199 idProduct = 0x68a2 bcdDevice = 0x0006 iManufacturer = 0x0003 <Sierra Wireless, Incorporated> iProduct = 0x0002 <MC7700> iSerialNumber = 0x0004 <012810001234846> bNumConfigurations = 0x0001 (instead of 0x68a3 where u3g attached to the device) But when I load if_umb, no new devices or interfaces get created nor is there anything in dmesg. This is on RELENG13 if that makes a difference. -- You are receiving this mail because: You are the assignee for the bug.
