Hi, We are using the USB mass storage gadget driver in Linux and everything is working fairly well but sometimes we are finding that we are exceeding the 100mA limit (which I think is the default the host will provide) before Linux has had a change to enumerate the USB device at which point we ask for 500mA. We have tried to reduce the power by ensuring all clocks are turned off, devices not used disabled etc but can't seem to satisfy the 100mA limit. We were thinking that maybe we could enumerate the USB device during U-Boot at which point we know we are under the 100mA limit. Does anyone know a reason why this would not work? would at some point from U-Boot enumerating a new bMaxPower would the connection be reset and drop back to 100mA during the kernel startup? Are there any considerations that we would need to take care of in the kernel for this to work? Many Thanks, Martin.
