Whenever Nokia Asha 311 is connected to computer by USB cable, data transfer to other USB drives/devices get frozen, like I cannot copy files from my hard disk to USB drive or vice versa. I was able to reproduce this problem with Windows XP, Windows 7 and Ubuntu. I also tried reinstalling firmware 3 times but problem still persists. While my Nokia 6303i classic works without such problem.
Welcome to Nokia Support Discussions!
The problem may be caused by the fact that Nokia Asha 311 can be charged via USB. So, whenever you connect it to your computer, it will automatically start to charge.
In some cases, computers have only limited amount of power reserved for the USB, so the USB controller will have to prioritise and thus disable some the other USB devices. Try to disconnect some of the other USB devices before connecting your phone to see if it makes a difference.
Hope this helps!

I think you are right. USB Hub is allowing 500mA which is all allocated to Nokia phone, so it can't power up other devices while phone is in use. I only have 1 USB Hub (like most of the computers) which allows to connect 4 USB devices. If I try to copy file to other USB drive, DPC latency drops after few seconds. Can I minimize the power permanantely or buying this model is big mistake?
