**** BEGIN LOGGING AT Sun Nov 18 02:59:59 2012 Nov 18 17:22:10 my embedded linux computer kernel crashes every time I insert a USB 3G modem Nov 18 17:22:21 I've tried with 5 different 3G modems Nov 18 17:22:27 all with the same result Nov 18 17:22:40 other USB devices seem to work properly Nov 18 17:22:52 anyone got any experience with this? Nov 18 17:33:52 no dmesg log or similar? Nov 18 17:35:35 no, the crash is instantaniously Nov 18 17:35:59 I've tried adding a few printk's in the USB moddule, but I cannot seem to get it early enough to print something out Nov 18 17:36:02 before it crashes Nov 18 17:36:15 I couldn't even light a LED on the board Nov 18 17:36:41 you would think then it could be something like an overcurrent on the USB port or something, but it doesn't seem like that either Nov 18 17:38:50 just for sanities sake, I'd try it through a powered hub Nov 18 17:41:04 oh good idea Nov 18 17:43:30 oh fuck me it actually works Nov 18 17:43:34 a lot of devices seem to fail at usb power stuff, so if the usb devices draws too much, weird ass crashes happen Nov 18 17:43:35 why haven't I tried this any sooner Nov 18 17:43:39 jesus christ Nov 18 17:43:45 heh Nov 18 17:43:55 I can't seriously belive I didn't think of trying that Nov 18 17:44:37 thanks Nov 18 17:44:44 np :) Nov 18 17:44:57 soo many people had this issue with rpi Nov 18 17:45:07 right right Nov 18 17:45:22 well I have to get around this issue Nov 18 17:45:33 guess I could short out the overcurrent circuit Nov 18 17:47:36 do you know how pwople came around this issue on the rpi? Nov 18 17:47:43 did they simply just use the external hub? Nov 18 17:49:15 pretty much Nov 18 17:49:26 rpi people also changed newer revisions so it allows to provide more power Nov 18 17:49:33 hm alright Nov 18 17:49:57 yeah the problem with this embedded is that it's actually powered by a single USB cable :p Nov 18 17:50:12 it does however have a battery, so maybe it's enough with those combined **** ENDING LOGGING AT Mon Nov 19 02:59:59 2012
