I don't think this is clear enough in the device description, but the Broadcom chip set is Class 2. I also found that I can connect to all my BT devices, phone, Palm PDA and Bluetooth audio adapter. Not the case with my previous dongles. The software was slightly problematic. I had forgotten that with the Widcom/Broadcom stack you must not plug in the dongle to start with or even when asked, which results in the dongle not being detectable by the software. Despite this Windows XP was perfectly happy, recognising the device in Device Manager and reporting no problems. So I had to remove the sofware and re-install, plugging the dongle in when it had all finished. Windows then completed the process and all was well. Its about time Broadcom updated the manual to reflect this problem, which has been around for years. Incidently I had downloaded the latest update from the Broadcom website, but found it impossible to use this at the outset, because it expected the dongle to be installed already. So I used the version 5.6.0.7700 on the supplied CD. I am still on this which surprisingly is a bit clunky, so should perhaps upgrade. However not knowing what the latest version is like puts me off. However this issue shouldn't put anyone off the device which always has a good solid connection to many devices. Review: Te duur voor wat het is. - Te duur voor wat het maar is. Kocht daarna een bluetooth dongle van €15 en die werkt even goed, ook onder linux. ## Features - Connect your Computer/Laptop with Bluetooth Enabled Devices such as Mobile Phones, Printers, Headsets, Stereo headphones and others - Latest Bluetooth specification v4.0 Class 2 with low energy technology; Fully compatible with older Bluetooth equipment - Compatible with 32 bit and 64 bit Windows 10/ 8.1/ Windows 8 / Windows 7 / Vista / XP / Raspberry Pi / Linux PCs that do not have in-built Bluetooth. - Plug & Play installation in Windows 10, 8.1, 8 with default Bluetooth stack.
