RaspberryPi frustration

Wed Aug 22, 2012 9:07 pm

I'm not a whinger by nature and I am no expert but I have been a Linux user for many years - I maintain a "gateway" system for twenty users that employs DHCP server, WINS and shared directories (via SAMBA), an FTP server, an IP-based camera security system and SQUID caching proxy server. I have used Debian, Ubuntu, Mint and OpenSUSE distributions and could always get them to do what I want.

But... I am just about reaching the point where I am ready to give up on the two Rasspberry Pi's that a collegue and I own.

Our requirements are simple - we need the Raspberry Pi to work reliably with a keyboard, mouse, HDMI display and a USB Wireless Dongle under Raspbian.

We have had our Pi's for 4 weeks now and they are still not fully functional. It took 4 attempts for me to find a power supply that would reliable power the Pi's. Then I was faced with the repeating keyboard problem - I have tried 5 keyboards and they all exhibit the repeating keys problem to a greater or lesser extent. The latest problem is the Edimax wireless dongle - over the past week I have tried every means possible from forums, blogs etc and we cannot get them to work. In addition if I power up my Pi with the Edimax plugged in it hangs trying to populate /dev. This Edimax works perfectly on a Windows 7 (ugh!) laptop. I looked at some posts on this forum about installing the Edimax software and one went on for 29 pages - my brain tilted after 4 pages!

Does anyone have a simple way of getting the Edimax working on a Pi that I may be able to understand. Maybe I'm too thick and I will never get it to work :(

Both our Pi's sometimes just hang when running LXDE and as a consequence all work is lost :(

We have tried multiple SD cards - this makes no difference.

Oh... my Pi USB chip (?) gets so hot after it hass been on a couple of hours I cannot touch it for more that a second or so - is this normal, is it the cause of the problems.

End of whinge.

What power supply are you using? What keyboard are you using? No point bothering with anything else unless power, keyboard and mouse work OK.

I've used a Blackberry, HTC and TomTom chargers without issue. I'm surprised your Pi gets so hot. That doesn't seem right.

mouse, HDMI and some USBWiFi should work.

ALL keyboards have the sticky key problem....it's a closed source driver problem not a hardware thing.

this is normal...well it's a hardware bug but it should have no effect.

Were the SD cards you kept trying the same class? Only reason I ask is my RPi would work intermittently with my old card (Class 6) and get really really hot as well. I got an AData Class 10 and it works like a charm. Funny - ArchLinux ran just fine on the Class 6 card. I'd give that distribution a try before giving up.

Hi,

I'm glad I am not alone in having frustrations with the setup of the Pi.

I, too, want a useable wifi dongle. I have a TL-WN822N - some web references say it works fine straight out of the box - some give instructions for getting it to work - ALL WRONG. I've spent many hours trying without any glimmer of results. Works fine on Windows - a quick try on Mint 13 was unsuccessful.

With regard the keyboard problem, I've tried several (Microsoft, Logitech K260 and generic) finally got a Logitech K400 - it works well most of the time. After all the fiddling with the wifi dongle the keyboard now requires a re-insertion of the wireless receiver before it will work at all -looks like I need to reburn the SD card. This keyboard very occasionally shows the nasty dropped key and endless repeat problems. I feel that this is caused by some indeterminate hiccup in the LXDE system.

So, can someone recommend a USB wireless N dongle that really does work.

regards
Peter

I feel your pain, been there myself. The Pi is a pain in the a**e particularly with many USB devices. I fear many will judge Linux by their experience with the Pi.

The USB chip getting warm isn't really a problem. Its in spec to way above what your finger will stand. If you haven't done so already, get the latest Raspbian (Wheezy) Image, and update it with

Code: Select all

sudo apt-get update
sudo apt-get upgrade
It won't alleviate your problems but it will probably improve things, they are improving the drivers all the time (particulary the USB).

Plain keyboards & mice work best, and if my experience is anything to go by, no-name cheapos are OK. Avoid anything Microsoft & Logitech especially if they are at the fancy end of the market. USB webcams and Wifi adapters are a lottery, some will work, some won't and a lot 'half work'. All my stuff works perfectly if I plug it into my PC running Ubuntu, I wish the same were true of the Pi.

I haven't had any problems with SD cards, but being a cheapskate, they are all cheap class 4 devices - Sandisk and Samsung

Power is paramount. I use stuff from Ebay sold as Pi power supplies, despite one of them being out of spec (600 mA - purists will throw up their hands in horror) they all work fine.
Don't judge Linux by the Pi.......
I must not tread on too many sacred cows......
