Hmm, it DOES seem to work with UHCI_HCD (in other words, it works if I only have USB1.1 devices connected). Then probably I've had problems with USB2.0 devices connected, so maybe the EHCI_HCD driver is not suspend-safe? I will try that when at home. --=-xo5GigcqJYD6lrpw2eiU Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQBDBFYjJgD/6j32wUYRAgHGAJ4wB+zgIr2uJpx/MDzff5+rzGveHACeJ/4A 5Ym4uHYbF/aB/i2Eu34GB9g= =GVh/ -----END PGP SIGNATURE----- --=-xo5GigcqJYD6lrpw2eiU-- ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf
