Hi,
My board BSP is base on BSP_WINCE_ARM_A8_01_02_00. WinCE6.0R3
we met a problem in ehcipdd driver when system suspend and resume,we connect a ULPI PHY tusb1210 to CPU-DM3730 USBHOST2 port.
the first time suspend it work well.we got about 10mA less current consumption. and then resume,everything is OK
the second time, suspend is OK,but we got about 60mA less current consumption, and then resume, system always die, or sometime printout Data Abort message then die.
how to fix this problem?and we have found some web which has the similar problem。

this link has a fix to this issue, but it still cost much current consumption, for the bus clock don't shuntdown when suspend.
Does Anyone has any idea about this issue?
thank you!
