Question about Motorola Mobility RAZR V3
Unfortunately the only solution I know is to get the specific charger for the KRZR. The device's firmware is set to measure the impudence on the USB power line (which is slightly different than a "standard" USB power lead and will not charge unless that difference is detected.
One possibility would be to rip-apart your USB charging cable and solder a small resister into the power lead. You will have to play with the resistance in order to find a working combination.
In lieu of wasting much time and possibly money, I suggest to give-in to "big brother" and just buy the special KRZR charger. I hate being held captive as much as anyone, but unfortunately it's sometimes inevidable.

I dont think that this will help much, but mine said that the very first time i charged mine ( with the brand new charger it came with!!! ) and it still says that occassionally. but then the notice goes away , and it charges my phone.
