I'll try to be clearer: (Sorry my bad English)
1 - I bought the kit;
2 - I bought the Xbox 360 Wireless Gaming Receiver for Windows (I want to play wirelessly on my PC);
3 - Wireless Receiver on my PC + Xbox Wireles Controller = OK. Works very well. Play Batman Arkham City =)
4 - Battery Empty!! Ohh and now? Who can help me? tan-daaannnn.... The Kit Play & Charge!!!
5 - I put the charge cable in PC, and then in controller. The 4 lights flash;
6 - Appears "Xbox 360 Wireless Controller via Play & Charge Kit" in Device Manager;
7 - Wireless connection stops working;
8 - Oh! No! Kit sucks. Stop play (Joker liked). Charge. Green light. Unplug. No synchronization. I have to reconnect my controller.
For me: driver issue. =(
