The motherboard was made in 1996 and these cards are all much newer. One of the cards gives USB 2.0 support, but I'm not getting anywhere near USB 2.0 speed out of the USB 2.0 devices I plug into it. I wonder if the problem is the speed of the PCI bus that the USB controller is plugged into. I installed pciutils-2.1.11_1 and ran "lspci -vv" to get the following log. Should I be disturbed by the "66Mhz-" status on everything except the RAID card, which is "66MHz+"? Should I adjust the latency on anything? Should I stop plugging new cards into old boards? 00:00.0 Host bridge: Intel Corp. 430HX - 82439HX TXC [Triton II] (rev 02) Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR-
