Post by Hans Petter SelaskyPost by Milan ObuchHi,
I got this 3G modem, it is not recognised under FreeBSD (tested with
fresh 9-CURRENT).
I found no relevant information googling for "huawei e1752 freebsd",
but "huawei e1752 linux" got me
http://www.blogcatalog.com/blog/iwrite-2/dbbfb38ae5ef9ccef8540aad7f9edbd6

It looks like this is the message necessary for switching this device
into modem mode, but I have no idea how to issue such comm and. Also, for
my use I need to get this working under 8.0-RELEASE/STABLE.
The last 16-hex bytes of the message is a SCSI command. Please make a new
usb/usb_msctest.c
Then test and make a patch for usb/usbdevs and usb/serial/u3g.c .

Hmm, just to be sure I understand what you mean, I made following patches:

I am going to compile it and test, just sent now if you see something wrong
(well, as said, I am not 100 % I understood exactly what you mean).
