BrusbSib.sys incompatible driver

Hello Good Day,

I also have the same problem recently so i tried to copy paste the code and observed that it doesn't change anything so I changed it maybe this will also help you KRM1970.

So here's how I change it. I put the specific published name of the file I'm getting rid of instead of oem21.inf. I just copy paste the published name of the said file from my computer's memory integrity report.

Hope this helps.

check whats written and oem.inf files are the ones to delete.

For my device MFC-L2710DW brother told the problem lays in incompatible old PC-Fax-driver.

so when custom-installing he big package(only) uncheck PC-Fax.
i wonder why all the askers didnt find my detailed solution. maybe its hidden here. but surely it elsewhere maybe google or brotherforum must recheck.

just had a windows reset made.printer was gone. reinstalled the package doing it right (disabled pc-fax) but the driver still blocked activation of core protection.

I should certainly had to use the brother uninstaller.

before that when printing a disturbingh popup of a brother-app or command nerved me. tellingh for a diagnosis which was not necessary. no clue why.
fact is after every installation a new version(numbered +1) of these oem.inf files will be generated. they must be removed.
hope everything is finding them. maybe one must enable hidden folders.

pity i cannot lead you to my older entries in forums. since i had a datacrash. inf-file is lost somewhere.

but i have a post in sysopt. dec 21. brother helped and told about the PC-FAX driver-issue.
Brother printer-driver BrUsbSib.sys(oem94.inf) blocking Core Protection-win10s. (sysopt.com)

the brother uninstaller must be used!

1. try to activate core-protection. then you will see BrUsbSib.sys further down will be listed the oem-inf file (s)which must be removed. will try to post a detailed solution when i am going through all the steps mentioned here.
2. the problem is these files are hidden. link above.
3. brother told diabling pc-fax when packed is installed(in custom mode only) was the solution. but after installation i still saw a new oem-inf-file(if i dont err) which had to be removed. there are numembered consequitively oem1.inf oem2.inf etc.

Windows11の初期化で全て解決が出来ました。
