Don't you mean 0.5A ? Half a milliamp really isn't allowing all that
much :-)

IIRR, the USB bus specification states that devices may draw no more
than 500 millamps. The Alcatel modem is misdesigned, and operates out of
spec. It is, quite rightly, shut down by some boards, as they regard it
as a faulty device (which it is).
