Hello CF : Your laptop may have the same hardware as this one of my mine. There is probably a chipset nVidia go150 with a video card gForce. I put the hardware profile at the end of this mail. That can explain our problem with USB. Before SuSE 9.3 64 bits, I tried the SuSE 10.0 64 bits : bad experience (no PCMCIA working, full freeze with graphic nVidia driver, freeze of X server when reading DVD, ...). So I went back to 9.3. In parallel I work with a SuSE 9.2 64 bits without major problems. With 9.3, the full freeze with nVidia driver is still present (do you use nVidia driver). A way for understanding what happens is to use a 64 bits live-distrib (Kunbuntu ?). If no problem with USB for a similar kernel, all comes from SuSE kernel (to my mind). Colin : About SuSE 9.0 AMD64, I used it in the past on this same Asus laptop and USB worked almost fine : it only failed with some USB2 devices (for example my Sony H1 or some memor key).

I have a somewhat similar problem with my Compaq Presario 3140 AMD64 laptop and my 64-bit SuSE 10 . If I plug and unplug my cellphone (which looks like a dialup modem, utilizing the module cdc_acm) a few times, my whole USB system just dies. No hotplug events are recognized from any USB device (not just the cellphone) until I reboot. I have not tried the 32-bit kernel. Upgrading to 2.6.14 from the apt-get did not fix the problem. Can hardware be excluded as a cause for these problems? CF
