Hello,
I purchased Pan1721 (order code: 2291473) from farnell. I installed BLE-Stack (CC2541) driver from Texas instrument website. http://www.ti.com/tool/ble-stack. When i connect Pan1721 USB stick, it says USB doesn't recognized (unknown device). Then i tried to give path in Device manager to drivers folder, then it says, USB driver is up to date. It still says Unknown USB. Please help me in installing drivers. I downloaded PAN1720 USB demo for TI and installed software (Btool). Thanks
