In a recent upgrade to my laptop EHCI supported was added to my |
| 2 |
kernel, I thought that this would be a good thing because I have a USB |
| 3 |
2.0 external harddrive that I connect to my laptop for additional |
| 4 |
storage and media. I also use a Logitech Quickcam Deluxe for Notebooks |
| 5 |
which is a USB 1.1 device and since that upgrade I have had issues |
| 6 |
with the webcam being disconnected at random. After some research into |
| 7 |
the cause it appeared to be an issue with ehci support and usb 1.1 |
| 8 |
devices. My question is for my laptop, a dell inspiron e1405 with an |
| 9 |
intel ICH7 chipset is there a way to use both USB 2.0 support and USB |
| 10 |
1.1 support in a way that wont cause conflicts of my computer. the |
| 11 |
output of lspci is displayed below. Right now my current workaround is |
| 12 |
to have all usb support built as modules and ensure that ehci does not |
| 13 |
get loaded. Thanks guys |
