Just a thought here:

 

If we hook a 100 ohm resistor to ground on the 5V supply pin of the USB In connector, then the Kernel will

think that a 50mA device is hooked to the port and be “fat, dumb and happy”. No ?

 

It will think that your 1 watt Bluetooth or WiFi dongle is only drawing 50mA, but who cares ??

Subject: [Gumstix-users] USB Port Current limit in Kernel

 

Hi All;

 

According to Tom Calef, and others :

 

“If the power descriptor says that its max power > 100mA then the kernel will yell at you

saying that its above the recommended amount.

I've been trying to figure out where to shut this check off, but with no avail.

 

-Tom”

 

See: “External power for USB” thread

 

Does anybody know a way around this ??

 

Is there another list I could post this question on ??

 

Bill
