Linux ASL 2.4.19-1 kernel or higher is required to support the onboard Ultra ATA/100 controllers. Using any other kernel will result in very poor disk transfer rate. USB USB 2.0 requires the runtime module ehci-hcd found in ASL 2.4.19-1 kernel or greater. This driver replaces usb-uhci, which is the default USB 1.1 driver. ASL recommends using the USB 2.0 driver for optimal performance. As shown below, USB 2.0 provides superior performance over USB 1.1 interface: Hdparm Iomega ZIP 750 with 750MB cartridge = 6.08MB/s (USB 2.0 mode) Iomega ZIP 750 with 750MB cartridge = 977.57KB/s (USB 1.1 mode) In addition, external CDRW drives featuring high speed USB 2.0 will only burn successfully using ehci-hcd driver. |
