Many people have encountered problems with error messages saying that this file: seehcri.sys has caused an unexpected error and it also makes some of your USB ports not working. The program Sony Ericsson PC Suite, specially the live update service seems to be controlling the USB controllers somehow by creating a virtual one "Sony Ericsson seehcri Device Driver" ; or that is how many people understand the problem.

Let's talk about some solutions available, some of which I tried and worked. First thing to do is to uninstall/delete these device drivers from your device manager, right click on My computer then choose properties and then you will find device manager on the left.

After doing that, many people found that the problem is solved by only deleting the "update service" that comes with the PC suite software. You can find it by going to Control Panel > Programs and Features and then look for "update service" and uninstall it. No find the seehcri.sys file and delete it manually if it is still there, I think it was under c:\windows\system32\drivers.

Now restart your computer and go to your device manager again and roll back the drivers. Some people still faced problems after this and had to remove every seehcri.sys entry from the registry.

If the problem still exist you can try removing the Sony Ericsson PC suite software using an uninstaller like Revo Uninstaller in the advanced mode which will delete all the files that has to do with the program and then you should roll back the drivers, but this time try deleting all the USB drivers and rolling back after restarting.

I didn't have to do this last step myself as the problem was solved after deleting the drivers and the update service and the registry keys that contain the file.

Please share the result with us in the comments section below, tell us which method have worked for you or if you have a new idea/method that can solve this problem. Thanks! :)
