The SIRF GPS units use the Prolific chips. I have had mixed results with them on Linux. They don't work like I expect when I try to use several of them on a high speed hub. The Prolific chip wants some guaranteed bandwidth and Linux has troubles allocating it. I thought I found a kernel option to get around that, CONFIG_USB_EHCI_TT_NEWSCHED, but I tried to clean things up last night and mumble. I guess it helps but not as much as I though. Mumble. It may be the hub-hub case that doesn't work. I've got a 7 port hub which is really 2 4 port hubs chained. I haven't noticed any troubles without the hub. I'm not doing anything fancy. -- These are my opinions, not necessarily my employer's.
