Yes, the 3.4.9 .config has nearly all of those. |
| 31 |
However, I'm not sure that your logic is the right way round (smile): |
| 32 |
something is telling Kernel + Udev to recognise only a 3.0 mouse, |
| 33 |
whereas Mageia/SR recognise a 2.0 mouse ; the mouse is 2012 , |
| 34 |
so perhaps it will function either way, depending on software. |
| 35 |
Why would K+U not recognise a 2.0 mouse ? |
| 36 |
|
| 37 |
That also suggests that if I plug a USB stick into those 2 back ports, |
| 38 |
it will give faster transfer speed ; the front ports are 2.0/1.1 . |
| 39 |
Is it safe to test that ? -- ie I don't want to ruin a stick. |
