March 11, Ask a new question. Hi, after a fresh install of windows 10 pro, I found these 3 drivers to have exclamation marks next to them in device manager. After just getting over a load of trouble with my computer, I'm dubious about installing anything. However, today I found that my USB ports will charge my phone but wont let me access any of the files on my phone. So I'm wondering if these 3 drivers are anything to do with that problem. If they're not anything to do with USB ports, could somebody tell me what they are to do with and if they are important. I have reluctantly been to manufacturer's website and downloaded and installed they're recommended drivers, which didn't fix my issue. Many thanks! Was this reply helpful? Yes No. Sorry this didn't help.
