Solution Type Problem Resolution Sure Solution 1001841.1 : How to configuring a USB 2.0 device under Solaris[TM].
PreviouslyPublishedAs 202519 Symptoms My USB 2.0 device which is attached to a builtin USB port on a SUN[TM] machine has a performance problem but performance is fine when attached to a PC. Resolution Currently, SUN machines equipped with builtin USB root hubs only support USB 1.x Low Speed (LS) 1.5Mb/s and Full Speed (FS) 12Mb/s not USB 2.0 High Speed(HS) 480Mb/s. When a USB 2.0 device is attached the maximum throughput speed the device will achieve is 12Mb/s (FS). Though, the internal USB ports don't support USB 2.0 it is possible to attach a 2.0 device and achieve High Speed (480Mb/s) throughput using a USB 2.0 pci addon card available through SUN. SUN Hardware Requirements -------------------- 1.) IEEE 1394/USB Combo Card. (Note 1.) (Note. 2) 2.) PCI based sun4u architecture system with available 3.3/5V 32Bit 33MHz slot. Notes. 1. The IEEE1394/USB Combo board is factory installed in Sun Blade 1500 and 2500 slot PCI 0. SUN part number 375-3140 with option 5414. Comes with 3-1394 Firewire ports and 5-USB 2.0 ports. 2. Some third party USB 2.0 addon cards may work inplace of Sun's Combo card. Check www.sun.com/io for a list of Solaris supported PCI USB 2.0 cards. SUN Software Requirements ------------------- Solaris 8 HW 5/03 PSR2 or Solaris 8 with patch 109896-13 or later. Additional Information To identify if current SUN[TM] machine has a USB 2.0 addon card and SUN's 2.0 USB drivers loaded run 'prtconf -D'.
