## Questions & Answers

**Q: Does this use the Toshiba Bluetooth Stack?**
A: No.  It uses the CSR Harmony stack.  CSR Harmony is the only stack that will support aptX.Jim

**Q: Will this work with Windows 10?**
A: It may be the answer too late. it works fine with windows 10 with its native driver but I don't know CSR Apt-X is working or not.
After updated to Win 10 Apt-x pop-up is disappeared and there is no confirmation this is connected with Apt-X or not. Anyway it is working fine for 4 years with my PC.

**Q: Does this dongle also supports hid profile? (for mice & kb) it's not advertised @ their web page.**
A: Yes.  These are listed in my Windows 10 "My Bluetooth Services" list (at the very top of the list).

**Q: Is this backwards compatible with older bluetooth versions 2.0, 2.1 and 3.0? Also can you pair a keyboard and a headset at the same time?**
A: Yes, it's compatible with all older bluetooth.  Yes, you can pair keyboard, mouse and headset at the same time, no problem here.
