| VarmVaffel | my embedded linux computer kernel crashes every time I insert a USB 3G modem | 17:22 |
|---|---|---|
| VarmVaffel | I've tried with 5 different 3G modems | 17:22 |
| VarmVaffel | all with the same result | 17:22 |
| VarmVaffel | other USB devices seem to work properly | 17:22 |
| VarmVaffel | anyone got any experience with this? | 17:22 |
| RaYmAn | no dmesg log or similar? | 17:33 |
| VarmVaffel | no, the crash is instantaniously | 17:35 |
| VarmVaffel | 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 | 17:35 |
| VarmVaffel | before it crashes | 17:36 |
| VarmVaffel | I couldn't even light a LED on the board | 17:36 |
| VarmVaffel | 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 | 17:36 |
| RaYmAn | just for sanities sake, I'd try it through a powered hub | 17:38 |
| VarmVaffel | oh good idea | 17:41 |
| VarmVaffel | oh fuck me it actually works | 17:43 |
| RaYmAn | a lot of devices seem to fail at usb power stuff, so if the usb devices draws too much, weird ass crashes happen | 17:43 |
| VarmVaffel | why haven't I tried this any sooner | 17:43 |
| VarmVaffel | jesus christ | 17:43 |
| RaYmAn | heh | 17:43 |
| VarmVaffel | I can't seriously belive I didn't think of trying that | 17:43 |
| VarmVaffel | thanks | 17:44 |
| RaYmAn | np :) | 17:44 |
| RaYmAn | soo many people had this issue with rpi | 17:44 |
| VarmVaffel | right right | 17:45 |
| VarmVaffel | well I have to get around this issue | 17:45 |
| VarmVaffel | guess I could short out the overcurrent circuit | 17:45 |
| VarmVaffel | do you know how pwople came around this issue on the rpi? | 17:47 |
| VarmVaffel | did they simply just use the external hub? | 17:47 |
| RaYmAn | pretty much | 17:49 |
| RaYmAn | rpi people also changed newer revisions so it allows to provide more power | 17:49 |
| VarmVaffel | hm alright | 17:49 |
| VarmVaffel | yeah the problem with this embedded is that it's actually powered by a single USB cable :p | 17:49 |
| VarmVaffel | it does however have a battery, so maybe it's enough with those combined | 17:50 |
