Chiefian Posted June 27, 2018 Share Posted June 27, 2018 We have multiple VR ready machines, as well as multiple Vives. All are working fine. However our Vive Pro has suddenly stopped working this week, and it says "BCM2045A0 Drive is unavailable" on any machine we plug it in. It was working last week, and then there was a Windows 10 update - and since then it seems to have stopped being recognised in Windows 10. Any help would be greatly appreciated.

HackPerception Posted June 27, 2018 Share Posted June 27, 2018 , similar error messages are typically associated with a bum bluetooth driver; the fact that it is consistent across multiple PCs a a bit concerning. Have you tried reinstalling the Vive drivers on a system? You can uninstall them by unplugging the linkbox, navigating to SteamVR>Settings>Developer and clicking "Remove all SteamVR USB Devices" followed by a system reboot.

odmlover Posted June 28, 2018 Share Posted June 28, 2018 You can also reinstall the bluetooth driver. Go to Windows Device Manager and uninstall the Bluetooth device BCM2045A0. You will see a Bluetooth device warning after a relaunch of SteamVR, click the the warning to install the Bluetooth driver. Link to comment Share on other sites More sharing options...
Chiefian Posted June 28, 2018 Author Share Posted June 28, 2018 Hey guys, Thanks for posting so quickly! What I found, much to my dismay was this was user error in the end. The cable on that is plugged in on the top of the Pro had come loose, either partially or fully. Once I unplugged that and plugged it back in again firmly it worked straight away. Thanks again!

sarseneau Posted May 22, 2019 Share Posted May 22, 2019 Having the same issue. Vive-Pro: green light and works fine on PC#1 (Windows 7 Pro) / GTX 980 Same exact HMD with associated cables, etc. Vive-Pro: red light on PC#2 (Windows 10 Home) / GTX 1080 Ti In device manager, under 'Other devices', the same 'BCM2045A0' is coming up as "no compatible drivers for this device." I've already: * uninstalled all drivers, reseated cables, drivers auto-loaded (except for the above) * specifically uninstalled the BCM.. from device manager and updated (no driver found) Google shows that this driver on Dell.com as a download but then Windows 10 complains that this is not supported. Help? Link to comment Share on other sites More sharing options...
Synthesis Posted May 22, 2019 Share Posted May 22, 2019 Just to check, make sure you're downloading the Windows 10 version of the driver rather than a different version. What's the link you're looking at for the download? Thank you, -John C Link to comment Share on other sites More sharing options...
sarseneau Posted May 22, 2019 Share Posted May 22, 2019 Thanks, figured it out, it was user error (extra file in Steam that prevented functionality), back to working Link to comment Share on other sites More sharing options...
