Thank you for your reply, Scroller! |
| 47 |
I used usbview to check for the kind of connection to the camera: |
| 48 |
480 MBit/s (HighSpeed). |
| 49 |
The bus the cam is using is not used by anything else... |
| 50 |
|
| 51 |
Sometimes it completly locks up an gstreamer, which is used by cheese, |
| 52 |
sends its test-picture... |
| 53 |
|
| 54 |
There NO technical specifications in the booklet of the cam. |
| 55 |
|
| 56 |
I wonder why... |
| 57 |
|
| 58 |
What's about the pictire quality of the Playstation "Eye" Cam, |
| 59 |
Scroller? Ok? Good? Better? Best??? ;))) |
