Win7 on Virtualbox 6.1 in IOS Macbook Pro with GPU AMD disabled - USB ports dead...
Posted: 7. Apr 2021, 17:42
Hello everyone
I have an macbook pro 15" (2011) where I uninstalled the GPU Graphic AMD by TIRESIAS 2 (modification hardware)...
I had to make the change because the pc had stopped working due to the defect of AMD...
After this, I install the Virtualbox 6.1 and second Win7 32 bit, all ok bat the two USB ports are not present...
I followed the various solutions in this forum with no results...
-------------------------
(A) To manually remove the AMD USB controller:
1. Open the Windows registry, by clicking Start > Run and typing regedit.
2. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000} .
3. In the right hand panel, if the the UpperFilters entry exists, delete it.
4. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ .
5. Delete the usbfilter string.
6. Close the Registry
7. Delete this file: %system32%\drivers\usbfilter.sys.
8. Reboot your computer.
-------------------------
(B) You can also use the ATI Catalyst Install Manager to uninstall AMD USB controller.
To do so:
1. Open Control Panel.
2. Open Add/Remove Programs (XP) or Programs and Features (Vista/7).
3. Double-click ATI Catalyst Install Manager or click Change.
4. Select Uninstall Manager.
5. Choose a Custom.
6. Select the AMD USB controller as the component to uninstall.
7. Reboot if prompted.
-------------------------
In the first case (A) the files (to delete) in "regedit" are not present...
In second case (B) when I try to continue uninstal manager, Catalist reply not files found...
Can you help me?
