Digest of /var/log/messages
I've bought a new USB card and it has not changed anything. I guess other hardware problems are a possibility e.g. something on the motherboard. However, I came up against a situation where it would not work with either the 766 or 770 kernels and I fixed it by booting Red Hat 8.0 with kernel 2.4.18-14, successfully using the modem and the rebooting with Fedora (and the 766 kernel). It is possible that when the modem is switched on it does not work with Fedora until it is first used with Red Hat 8.0 and kernel 2.4.18-14 or with Windoze. The other possibility is that powering down the computer changes state in the USB hardware but I don't think that explains the experiences I have had. I will post again if I make progress but it all takes time and actually I posted this bug because I was looking for an expert opinion, so I am not sure I should bother ;-) My original modem has now been returned and they found no problem (but updated the firmware). So I think failure under windoze etc. was an illusion. However comment #2 paragraph 3 appears true. Problem occurs with 2.6.10-1.766_FC3 and 2.6.10-1.770_FC3 kernels but not 2.4.18-14 (and RH 8.0) or Windows XP and supplier drivers. Note that since the modem is supposed to provide modile internet, it has a rechargeable battery like a mobile phone and there is rarely a need to switch it off. I will attach standard output of lsusb -v. BTW it gave me this on stderr: cannot peek string descriptor 3, error = Broken pipe(32) Let me know if anyone wants anything else.

Output of lsusb -v -s 0004:002
stderr had: cannot peek string descriptor 3, error = Broken pipe(32)
This is fixed in 2.6.11-1.14_FC3 kernel. (Not sure whether resolution should be CURRENTRELEASE or RAWHIDE in that case.) |
