Hello,

Machine Stats:

Win7 Pro x64
Gigabyte P55-USB3 Motherboard

You may have to baby me through this, this is my very first programmable device of this nature, never used Arduino...

I just received my digispark, downloaded the IDE (1.03 uploaded on 1-5-13). I installed the driver by running InstallDriver.exe, and it said libusb-win32 Digispark Bootloader was "Ready to use".

I check the event log:
Successfully created restore point (Process = C:\Windows\system32\DrvInst.exe "4" "0" "C:\Users\deranjer\AppData\Local\Temp\{1153b1bb-4e5a-2596-a518-a258a518a258}\digispark_bootloader.inf" "9" "64bc5de07" "00000000000004E0" "WinSta0\Default" "00000000000005A8" "208" "c:\users\deranjer\appdata\local\temp\7zipsfx_000"; Description = Device Driver Package Install: libusb-win32).

I started up Arduino 1.03 and went to Tools, set board to Digispark(tiny core) and programmer to Digispark. I opened the digispark example program "start". I did file->upload. It told me to plug in device now. I plug in the device, and nothing happens, try another USB port and then I get "USB device not recognized, may have malfunctioned, etc etc" I try the back USB 2.0 ports, same error, or no response. I grab an unpowered USB hub, still get USB device not recognized. Sometimes it seems to recognize it and asks me to install the driver, which should already be installed. Sometimes I get zero response at all. Arduino never moves past "Plug in device now" (On the bottom right it says Digispark (Tiny Core) on COM1 I did reboot and try again, same result. I even try USB 3.0 ports, no response at all.

Nothing notable shows up in the event log.

I do not have another digispark to try, only the one.

I then moved over to my wife's linux box, running Ubuntu 12.10.

I followed the wiki steps and compiled the necessary executables, (as far as I can tell, I am not as proficient in linux as Windows)

I started up Arduino (as root "sudo ./arduino"), set Digispark (Tiny Core) and programmer, loaded the blink example, and was met with plug in device now... plugged it in, again, no response. Did #lsusb, nothing listed, tail -25 dmesg, nothing appeared in there...

Setup UDEV rules in the linux as shown in the linux troubleshooting page, still nothing.

Do I have a bad device, or am I doing something wrong?

@deranjer - you might have a bad one - but the fact that you get an \"Install Driver\" prompt suggests to me that it is working. I very much appreciate that it seems you went through all the troubleshooting steps. Do you have access to a second windows machine you can test with? If you do, it would be great to test on a second machine - I\'ve seen a few cases where it did not work on one machine and then worked on a second one, and then we were able to get it to work on the first.

So if you can try that that would be great. If it is a bad one we will replace it.

The only other windows machine I have is a Virtualbox VM Guest (Windows XP x64) that I use for work. I did try that, but when I capture the USB device, it pulls it in as a USB video device, and since it is obviously using the same hardware I didn\'t bother doing much troubleshooting on that.

The odd part is how inconsistent it is... Every 1 in 20 times it seems to recognize and attempt to install drivers. Then it is split between zero response when plugging it in, and saying \"USB device not recognized\"

I will attempt to borrow a Windows laptop from a friend and test it on that.

Thanks

@digistump - So I tried it on my friends Win7 32 bit laptop. The Installdriver.exe installed fine, so I started the example program after setting the correct settings. At first I had zero response at all until I plugged in the USB hub and plugged the digispark into there and it did recognize it, but it immediately said \"USB device not recognized\". Tried it multiple times, got the same error, or it would attempt to install drivers, but they would not be found.

Do you have any more ideas? If not, how do I go about getting a replacement?

@deranjer - I\'m not totally convinced this is a bad Digispark, but something is obviously a-miss here - so I think it makes the most sense to get you a replacement, please email me your name, email, and if you have it - order id at support at digistump dot com - and we can go from there.

Thanks!
