1  Hardware and U-Boot firmware / Hardware / Re: Guruplug Wifi -- utterly broken? on: March 01, 2011, 04:12:43 PM
anyone reading this who has not found the solution should check out the excellent work by Strav here
http://www.newit.co.uk/forum/index.php/topic,455.15.html

and here where he has written it up for the wiki
http://www.plugcomputer.org/plugwiki/index.php/Setting_GuruPlug_to_be_a_stable_WiFi_Client

With these changes made, my script (see above) can run for over 90 minutes without crashing the Guruplug where before it was not lasting more than 2 minutes.

When I boot the device with the device already connected, it has a similar response, but I CAN fdisk and see the device. I can then mount it too:

hub 1-0:1.0: unable to enumerate USB device on port 1

I did have the same error -71 with an SD card reader, but it was resolved for that device by adding the usbmount package. The package makes no difference when connecting the Viewty. My Sony PSP connects every time, with and without usbmount.

I have copied the udev rules, .conf and usbmount settings from the Guruplug to the Nimbuses with the same errors occurring

The Viewty also connects fine to the Sheevaplug which doesn’t have usbmount. I copied udev rules from that to the Nimbus, but no change when plugging the Viewty in.

A search of the web suggests that this Error -71 issue is most often caused by a lack of power. I have tested the hardware. The Nimbues are delivering 5.21V on the USB when unconnected, dropping to 5.01V when I plug in the viewty. I have added supplemental power from an SMPS (in case the current was insufficient) but this makes no difference to the connection.

What is wrong and how can I fix it?
3  Hardware and U-Boot firmware / Hardware / IONICS Nimbus 100 Development Kit - USB error -71 on: November 11, 2010, 11:46:17 AM
Is anyone aware of any issues with the USB signal from the Nimbus 100 Development kit?

I have been using the Nimbus 100 Development Kit. I have a problem I cannot solve with one of my USB test devices. I get the same problem, every time I connect this device and cable to a Nimbus 100. I have two Nimbuses and the results are identical on both.

I have three test devices, two of them always connect properly on both Nimbuses. The problem device never connects to either of the Nimbuses.

I also have Guruplugs and older GlobalScale Sheevaplug and have done back to back testing of this issue on those devices. The problem device (an LG Viewty phone) connects correctly to my 2 x Guruplugs, the Sheevaplug, my Linux Development Host, my Windows PC and an ATMEL based plug computer that I have also built.

I have tried as many different linux distributions as I can on the Nimbuses and under each, the Nimbus plugs fail to connect the LG Viewty. Both Nimbuses have exactly the same issue. The phone connects to the Guruplug ok and another Sheevaplug. I have tried those kernel / RFSs on the Nimbuses and I still have the same problem.

Code:

The “PEC” is bad news as I understand it

When I do usb start in uboot, the device is not found, even though the screen device screen says it is in mass storage mode.

4  Hardware and U-Boot firmware / Hardware / Re: GuruPlug Server Plus - will my scenario work? on: November 11, 2010, 10:04:14 AM
The fan is so loud that I can hear mine from the opposite corner of a 5 bedroom house. Shocked

I have measured it at 70dB, compared to my desktop PC at ~50dB.
5  Hardware and U-Boot firmware / Hardware / Re: Guruplug Wifi -- utterly broken? on: November 11, 2010, 09:56:04 AM
Does anyone know of any patched libertas drivers or 8688 firmware?

I can certainly confirm that the Guruplug will not work for very long as a WiFi client with the factory distribution. I have also tried recompliling using the sources published with no difference.

I created a really simple script. I have two Guruplugs and the same happens on both. When I run this on a Guruplug connected ONLY via wifi to my home router, the Guruplug crashes - typically after 1 - 2 minutes. There is no error when using ethernet of course!

Code:
#!/bin/sh

while [ 1 ]
do
wget ftp://192.168.1.101/Downloads/datasheet.pdf
rm datasheet.pdf
echo "done"
done
exit 0

The same error occurs when using curl to download instead of wget (so it is not the wget package), but it works when I copy the file from one directory to another (ie eliminating the wifi element of the test).

This is the failure I see
