USB problems; USB devices do not mount

[Kathrin Slawik]

hello everyone, i have a problem that my usb port doesnt recognize any device anymore (mouse / hard drive) but i can still charge eg a phone over it. 

 

i found this topic here: 

 

 

i tried to read through all the pages but honestly im a pretty newbie with this topic and its a bit difficult for me. i hope someone here can help me a bit and guide me to fix my problem. im using a macbookair with catalina 10.15.7 (more infos necessary?)

 

i tried already to see if the darwin Kernel Version (19.6.0) fit with the one in system.kext and they do. i tried to download the USB Fix but the file isnt ava anymore. i checked already for the PCGENUSB2 and i dont have it installed. i also tried to contact LioNEXT via PM but it seems he isnt active here anymore....

 

if i type in 

sudo kextunload IOUSBMassStorageClass.kext  

 

i get the follwing error message: 

 

Unable to determine realpath for /Users/kathrin/IOUSBMassStorageClass.kext - failing.

Can't create IOUSBMassStorageClass.kext.

 

 

if i type in kextstat | grep "USB"

 

i get

if i type in 

 sudo kextload -b com.apple.driver.AppleUSBComposite

 sudo kextload -b com.apple.iokit.IOUSBMassStorageClass

 

nothing change

 

 

 

UPDATE 

i reinstall macos and nothing changed (but keeping my datas). i already reset SMC and NVRAM also here nothing changed. its interesting if the mouse is plugged in and i restart the mac the mouse lights up for a few seconds and then turns dark when the laptop boots... 

 

not sure if you can help me any further but it would be incredible as i really need my usb port back.... 

 

thanks so much for any advise you can give me.

Without signature I can't say something.

You are having this issue on an Apple MacBook Air (MacBookAir5,1) mid 2012 and it should support macOS Catalina officially right?

If you can do a clean install because you don't need to do anything special to have the USB ports working.

 

If my assumption is correct you need to back up you data and do a clean install or just boot your MacBook Air from a USB disk if you can and see if the USB ports are working properly.

I have exactly the same problem as of dec 20 2023! I cannot use anything on all my 4 ports; mouse, keyboard, sd card ... but charging is fine. 

I see the file IOUSBMassStorageClass.kext is missing on my macbook pro 2019 using macOS 14.3.1. 

Is a clean install the only option here? 

Thanks,

Linda
