Hi Ajay, I have tested with USB hard disk and getting ~264 Mbps. Is there any option/method to increase the performance? with regards Ganeshan ----- Original Message ---- From: Ganeshan N <nganeshan1@xxxxxxxxx> To: "Gupta, Ajay Kumar" <ajay.gupta@xxxxxx>; "linux-omap@xxxxxxxxxxxxxxx" <linux-omap@xxxxxxxxxxxxxxx> Sent: Wednesday, February 4, 2009 11:34:14 AM Subject: Re: OMAP3 EHCI USB HS mode performance issue Hi Ajay, Thanks a lot for your valuable inputs.

I have tried with pen drive with different manufacturer > (Tanscend, SanDisk, Kingston). I am using OMAP35x EVM. We have observed lower throughput with pen drive so it's better if you take the performance numbers from any USB hard disk. I think you are using OMAP35x EVM with Mistral daughter card. With Mistral DC, I am getting a read/write throughput of ~160Mbps on EHCI with USB HDD and CPUIDLE=off.
