Which are those exactly? Debian or Redhat based are most preferable.or use a different distro, there are many to choose from that uses the dwc2 (USB 2.0) driver.
And supported by Rasberry PI 1 (for example Ubuntu is not).

Re: Compiling from source on Raspberry Pi 2 on latest raspbiI would love to know as well. Even for RasperrbyPi2's. For what it is worth I have just noticed that Ubuntu snappy just looks like it has been refreshed for the Pi so I guess I should summon up the fortitude and experiment with that to see if it is any better? I am not sure what state plain "debian jessie" vs "raspberian jessie" differ for the pi as well. In the end for my situation I just still use the standard usb-modeswitch which is installed in rasperian wheezy. (I haven't yet moved to Jessie since there are problems with Chromium on jessie. (https://www.raspberrypi.org/forums/view ... 9&p=751381, http://conoroneill.net/running-the-late ... erry-pi-2/ but apparently there is no hardware acceleration of Chromium with that...) In any case I should try usb-modeswitch with rasperian jessie but I haven't yet (it is on my list of things to do) Instead to work around the problems I had with usb-modeswitch I used the method given here: http://raspberrypi.stackexchange.com/qu ... g-a-script Then I have lots of watchdog scripts running which see if the modem didn't come up, and if it didn't then the pi is rebooted. I wish I could get this more stable but I have thrown oodles of time at it. I am kind of stunned it was so difficult. With the whole IOT and using Pi's as development embedded devices to communicate I would have imagined there would be some rock-solid way to basically use a 3G modem / communications somehow. I am yet to find it if there is and would love to know if I have missed something simple... Thanks, Jason Re: Compiling from source on Raspberry Pi 2 on latest raspbiThe problem can also be an insufficient power supply of USB devices on the Pi. There were reports giving hints that using a powered USB hub improved reliability.

It turns out during the ongoing development of our units, that for a while now we have had a custom power supply in our units which have the included raspberry Pi's. Thus now we can control the power levels quite accurately. This has not solved the "intermittent-ness" of problem for us. Josh, do you happen to know if there are changes in raspberian Jessie, re the USB handling / usb_modeswitch? Thanks! Jason |
