Dear sir: No, We don't use USB for we cannot get in touch with the machine right now. We connect to the machine with IMPL network, and insert the stx boot image with function called "virtual storage" in the ikvm environment. Do we have to plug the USB into the machine physically? yours, zhou qingyang 在 2020-04-29 12:01:25，"Penney, Don" <Don.Penney@windriver.com> 写道： Can you provide details about how you’re trying to install?
