Aidan. 0 Posted November 28, 2020 My cosmos used to work perfectly but now whenever i plug in my headsets HDMI it says "Setting up device QUSB_BULK then says "Drivers unavailable" and then proceeds to not work and have 108 errors for steamvr and 001 errors for vive console. Any help would be appreciated i have tried wiping all data and uninstalling vive console and steamvr and all other reccomened options. Thanks! Share this post Link to post Share on other sites

Sasavane 0 Posted November 30, 2020 Ahhh...I remember there is no HDMI on my Cosmos adapter and I don't think it supports HDMI either. Share this post Link to post Share on other sites
VibrantNebula 219 Posted November 30, 2020 @Aidan Are you using HDMI or Displayport? You can never use HDMI port with Displayport driven headsets like the Cosmos/Pro and doing so will certainly result in a 108 error. The QUSB_BULK message references a corrupt driver but that driver is specific to Qualcomm devices. @C.T. Share this post Link to post Share on other sites
C.T. 100 Posted December 1, 2020 Can you supply an issue report to me and provide the trace number? Share this post Link to post Share on other sites
slobba 0 Posted December 19, 2020 Did you get a resolution to your issue? I am having a similar problem with my Cosmos headset. Error 001 Headset not connected in Vive Console and the following in Devices when the headset is plugged in: I have opened an issue report via Vive console but last email from Technical Support has stated that "Based on the driver's details that you have provided it indicates that some of your cables are having a problem which leads to drivers issue or misbehaves". I am skeptical that they can determine that this issue is caused by a faulty cable, and not a faulty headset, just by the 'driver's details'. Thanks. Share this post Link to post Share on other sites
