The product name is "USB 2.0". > But as I mentioned before, it shows up in the dmesg log as using > high-speed transfer: > > Apr 15 17:13:33 zeddicus usba: [ID 912658 kern.info] USB 2.0 device > (usb204,6025) operating at hi speed (USB 2.x) on USB 2.0 root hub: storage at > 4, scsa2usb0 at bus address 2 > Apr 15 17:13:33 zeddicus usba: [ID 349649 kern.info] CHIPSBNK USB 2.0 > 20800FCE05407 Yep, the Solaris usb kernel drivers are using usb 2.0 protocol. But when the bios reports something like "CHIPSBNK USB 2.0", it is just passing the usb manufacturer and product string; that "USB 2.0" product string doesn't tell us what protocol is currently in use by the device. It could be usb 2.0 protocol on an ehci controller, but it could also be usb 1.x on an ohci or uhci controller. -- This message posted from opensolaris.org
