📎 AI Summary:
The thread concerns a user experiencing periodic BSOD errors when connecting USB devices, with initial suspicion of a driver issue related to hcmon.sys, a VMware USB monitor driver. After troubleshooting and considering the removal of VMware software, subsequent BSODs persisted but were still linked to hcmon.sys. The overall sentiment indicates the user is hopeful that uninstalling VMware drivers will resolve the problem.

Hello,

I have the following problem - from time to time (it does not always happen) when I connect some USB device (pendrive, printer etc.) BSOD suddenly appears. Could you please help me? I'm attaching all the needed files (from W7F Diagnostic Tool, CPU-Z and RAMMon). Thank you in advance!

Hi,
every dmp file is the same. The file hcmon.sys is a USB VMware driver and if possible you need to update your VMware:

Hello,
Thank you for your reply and sorry for such a big delay in answering. Frankly, I think that I don't need VMware - I'll try to uninstall it and see if it helps. However, today I had another BSOD, without any USB connection. I'm sending a dmp file in an attachment - could you have a look please?

Hi,
removing the VMware stuff sounds ideal as the above hcmon.sys belongs to VMware and is a USB monitor driver.
