Sid, Thank you for the procedure. I just located the solution (in addition to yours). While this is NOT a recommended way to solve this, I pass this along in case anyone else fat fingers their distro with respect to updates. Even though I had updated 9.2 as of 31 Jan 2005, I did not reboot the laptop. Thus, I was still running the 2.6.8-5 version of the kernel rather than the 2.6.8-24.11 version. Big difference with respect to the USB Serial support. I noticed this once I started poking around in /boot and then comparing the dmesg file with 'uname -r'. I mistakenly figure that the 2.6.8-* versions of the kernel were similar enough that all the support for USB was there. Wrong assumption. Once I rebooted the laptop, the new kernel found and configured correctly the the USB cable, and MINICOM found /dev/ttyUSB0 without complaint. Here is the dmesg output: uhci_hcd 0000:00:1d.0: irq 11, io base 00001800 uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 1 usb usb1: Product: UHCI Host Controller usb usb1: Manufacturer: Linux 2.6.8-24.11-default uhci_hcd usb usb1: SerialNumber: 0000:00:1d.0 hub 1-0:1.0: USB hub found hub 1-0:1.0: 2 ports detected ACPI: PCI interrupt 0000:00:1d.1[B] -> GSI 11 (level, low) -> IRQ 11 uhci_hcd 0000:00:1d.1: UHCI Host Controller PCI: Setting latency timer of device 0000:00:1d.1 to 64 uhci_hcd 0000:00:1d.1: irq 11, io base 00001820 uhci_hcd 0000:00:1d.1: new USB bus registered, assigned bus number 2 usb usb2: Product: UHCI Host Controller usb usb2: Manufacturer: Linux 2.6.8-24.11-default uhci_hcd usb usb2: SerialNumber: 0000:00:1d.1 hub 2-0:1.0: USB hub found hub 2-0:1.0: 2 ports detected ACPI: PCI interrupt 0000:00:1d.2[C] -> GSI 11 (level, low) -> IRQ 11 uhci_hcd 0000:00:1d.2: UHCI Host Controller PCI: Setting latency timer of device 0000:00:1d.2 to 64 uhci_hcd 0000:00:1d.2: irq 11, io base 00001840 uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 3 usb usb3: Product: UHCI Host Controller usb usb3: Manufacturer: Linux 2.6.8-24.11-default uhci_hcd usb usb3: SerialNumber: 0000:00:1d.2 hub 3-0:1.0: USB hub found hub 3-0:1.0: 2 ports detected usb 2-1: new low speed USB device using address 2 usb 2-1: Product: Microsoft Trackball Optical usb 2-1: Manufacturer: Microsoft usb 2-2: new full speed USB device using address 3 * ***** See Here *** **usb 2-2: Product: USB SERIAL CANSERTOR usb 2-2: Manufacturer: FIDI usb 2-2: SerialNumber: FTBT8RZI* hw_random hardware driver 1.0.0 loaded ACPI: PCI interrupt 0000:00:1d.7[D] -> GSI 11 (level, low) -> IRQ 11 ehci_hcd 0000:00:1d.7: EHCI Host Controller PCI: Setting latency timer of device 0000:00:1d.7 to 64 ehci_hcd 0000:00:1d.7: irq 11, pci mem f9174000 ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 4 PCI: cache line size of 32 is not supported by device 0000:00:1d.7 ehci_hcd 0000:00:1d.7: USB 2.0 enabled, EHCI 1.00, driver 2004-May-10 usb usb4: Product: EHCI Host Controller usb usb4: Manufacturer: Linux 2.6.8-24.11-default ehci_hcd usb usb4: SerialNumber: 0000:00:1d.7 ....<snip> usb 2-2: USB disconnect, address 3 usb 2-1: new low speed USB device using address 4 usb 2-1: Product: Microsoft Trackball Optical usb 2-1: Manufacturer: Microsoft Adding 2096472k swap on /dev/hda3.

Folks,

I'm a bit stumped here and hope someone has seen this before.

I just bought a USB->serial cable from PCClub. It's advertised as a USB 2.0 Certified Interface (usbview diagrees with that), and SuSE does recognize it, but I can not get minicom to talk to it. When I set it to /dev/ttyUSB0 or any USB tagged port, it comes back and complains that the port is not found.

I have it plugged into the top USB slot of the laptop.

What I need it for is to configure telecom equipment that uses serial ports for the interface (VT100 9600/N/8/1). I've been playing with this for about a day and need to move on or get it to work.

Any suggestions would be appreciated. I'll even buy a different cable if there is one proven to work.

Thanks,

...Paul

Have a look at this article, this may be a way to do it, I may try it later. http://www.linuxjournal.com/article/6573 Regards Sid.

Hmmmm... surprise, it works - I have CONFIG_USB_SERIAL_GENERIC=y, but there may be a module for the SuSE kernels.
