Connection problem with KX1

[boriskin]

Hello all,

I'm working with KX1, everything was just fine when couple of days ago my PC simply refuse to recognize the phone. I've tried to reinstall USB drivers, played with serial port speed on the phone and PC, tried different drivers etc, but nothing helps. I thought its USB problem, but USB mouse works just fine from any socket. Cable is recognised and drivers are installed without problems as well, but phone is being ignored as if there is nothing on the other end of the cable. I didn't install any software recently, didn't change configuration and BIOS settings, so I don't have any clue what could lead to this situation.

I'm using KWC USB to K7 Cable (it was working fine too), phone has platform 2.1.1.2 , software 2.0.0.v1

Brew Logger (3.0.0.12) returns "Could not initialize device (Error Code 9)",
Brew AppLoader (3.0.0.12) returns "Could not connect to the device using specified device ID", version 1.0.31 returns "Could not open the specified port".

Phone is working with other PC, slowly and sometimes from 2nd-3rd attempt to connect, but as soon as you are connected to it - its 100% workable.

Any hints or ideas?
Thanks

Finally I fixed the problem, the other application that was affecting USB devices was the source of the problems. However, I still don't know why it just happened one day since that app has been around for quite a while.
