So first of all I just want to say "it has nothing to do with preview for developers". That's first.
Back then when I was using Lumia black (8), things seem to be fine.
After updating to 8.1 using preview for developers, yeah I live it very much. But I don't know what happened to my device. I was able to sideload stuff like, you know, install paid app for free. But that was for a while. Now I'm not able to do that anymore. Whenever I connect my device to PC, it keeps on showing device decriptor request failed.
DONT SAY "TRY USING DIFFERENT CABLE OR USB SLOT". I did ask those IT guys about it, but they seem stupid (no offend). All they told me was this line I mention in DONT SAY.
I have 5cables in my house, 2laptops and 1desktop, all with Nokia sdk, with total of 15 USB slots. I tried it all and it's not working.
I wish someone in here can help me since google couldn't. Sorry for my English.

Which Windows you have? Windows 8 or 8.1 x64 is recommended because WP SDK 8...

check solutions on Microsoft page: http://support.microsoft.com/kb/2749484

also try reinstall Nokia drivers, best to do this is to install Nokia Software Recovery Tool

I swear to god, I have windows 8.1 64 bit, all on 2laptop and 1 desktop. All have Nokia Software Update and Nokia care suite thing. Maybe last month, or 20 days, I did side load amazing spider man 2 just fine. But today, it's not reading my phone. Again, I swear, I did not install or uninstall anything on both laptops and desktop. It just suddenly stops working. Or maybe it uninstalled itself from all 2 laptops and 1 desktop?

Or an issue with the update. I was having all kinds of issues connecting to blue tooth devices after the update. A couple of hard resets and a fresh profile later and most of the kinks are worked out.

If all your computers and cords work, the only thing left is the device. It's either hardware or software, and the easiest thing to test is to put it into recovery mode and see if it detects it / can write to it.
