Hi all,
I recently updated my Dell Latitude E6440 (Intel Core i7-4600M, Intel HD Graphics 4600 + AMD ATI 8690M (not used)) from Catalina to Big Sur. When i connected flash drive, this message showed up:
akc usb needs power
Connect "Flash drive name" to USB port in this Mac
After installing USBInjectAll mouse receiver worked, but flash drives still didn't. Before updating to Big Sur, USB worked fine.
Old EFI: https://github.com/xiangagou/Dell-E6440-Hackintosh
New EFI: https://github.com/KD-AIP/Hackintosh-E6440/tree/BigSur_OC
config.plist with USBInjectAll: config.plist.zip
Any ideas how to fix this?
