Comment 13 for bug 1169117

Having the similar issue with Ericsson H5321gw in Toshiba Z830. SIM registers to network, but than fails to connect most of the tries(like 1success to 30 failures). I tried the solution in 2), after reboot I connected from the first try, but after that I have not be able to get connection.
I see the driver used in my case is cdc_acm - cna this be the reason?
