Dongles used are standard and mini Digitech brand.Several of the same brand. Only two different models of the same brand. A blue tooth dongle of the same brand does not cause a crash.jamesh wrote: I'm guessing its spiking the power somehow and causing a crash.

It also does NOT occur when using the wireless dongle in a usb hub (not powered) that is connected to the pijamesh wrote: Does the dongle work in a desktop when you do the same thing?There are plenty of occurrences when there is a need to remove the dongle.

The pi's are also connected to robots where kids are constantly picking them up a moving the dongle enough to cause a reboot.
I get reboots on a 256MB old Pi when I remove a wifi dongle from a Pi USB slot (that's why I don't remove it from the slot any more).jamesh wrote: ...

Just a bit of additional information - did all the dongle you tried have the same wireless chipset? It difficult to tell whether this is a hardware issue or a software issue, my inclination is power supply/HW since they work in a powered hub. Odd that wiggling them causes problems, that sort of indicates a connection problem in the USB connector.
How recent is your Pi BTW?
The two wifi dongles are:jamesh wrote:did all the dongle you tried have the same wireless chipset?
One made in china, 5 early UK, another 5 around 6 months old.jamesh wrote:How recent is your Pi BTW?

Yeah I tend to agree. But it's hard to argue the "fault" to a supplier when it 's only happening in one device.mikerr wrote:But if your USB devices are disconnecting when you wiggle them - that's a (design) fault of the devices not the Pi IMO.
Yeah, that's them.jdb wrote:When you say "small dongle" - is it one of the types that are not much bigger than the USB connector shell?
All of these issues really sound like OS issues. I would start with a fresh load of the 09-25-2013 Raspbian image and try again.ioudas wrote:Hi All,
I have several pi's that all have several major issues. Freezing, usb key stroke repeating, hdmi dvi resetting, transfers to the pi dropping over wired/wireless ssh drop outs. All products have been directly purchased on adafruit. I would like to know about the warranty/refund policy for pi's. I have tried multiple different power blocks, powered hubs etc.
When i remove wifi devices the pi will freeze and lock up permanently until a forced power reset is started, etc.
I imagine there is no refund policy directly from the pi foundation for these boards?
IME, it is not the unplugging that is a problem. It is the re-plugging.The solution: Don't unplug stuff. Seriously - that's the only solution.

Regardless of weather or not the OP deserved that, or if he was trolling - nobody, and I mean nobody deserves to have moderating power with such an appalling attitude towards the community. There's simply no need for that. The Pi forums are already a bloody hostile place as it is without the mods making it worse.Jessie wrote:Now if you want to get these working cut the crap and provide enough information for people to help you or close your pie hole.
I don't normally post on locked threads, but will do in this case. I agree that the response quoted in over the top, and I will have a word, but would be interested in why you think the forums here are a hostile place. The mods do try and keep things as polite and hostility free as possible - and compared with many other forums this has been fairly successful - we do need to be child friendly. This will of course vary by thread, some topics are by their nature, rather difficult, this one being a case in point. Here the OP has a problem, has made various claims, but hasn't given enough information to verify or to fix the problem despite being asked to provide that information. This is very frustrating, especially to those who spend a lot of time helping out here, who really do want to help.rmwebs wrote:Regardless of weather or not the OP deserved that, or if he was trolling - nobody, and I mean nobody deserves to have moderating power with such an appalling attitude towards the community.
