Thank you for contacting USGlobalSat Customer Care.
Unfortunately, due to the specific version of the PL2303 Prolific Chipset used in the BU-353, it will not be compatible with Windows 8 & Windows 8.1 & Windows 10.
Although, just recently, we may have found a work around, please refer to this forum post: BU-353 with Windows 8 & Windows 8.1
If you're looking for a USB GPS
Receiver that is fully compatible with Windows 8, Windows 8.1 & Windows 10,
we highly recommend the new BU-353-S4, which uses the new SiRF Star IV chipset that offers better performance, faster time to fix and better accuracy: USGlobalsat Corporate
Let me know if you have any questions.
