> I'm getting very slow writes: Part of the problem in this case is that the device isn't used with USB 2.0 protocol but the slower USB 1.x protocol. USB 1.x is limited to ~1MByte/sec. (And using pcfs on top of that makes things worse) Is that an old laptop? Maybe the USB controller doesn't really implement the newer USB 2.0? Are there any "ehci" USB 2.0 controllers listed with "prtconf -D | grep ehci" ? -- This message posted from opensolaris.org
