Fresco logic FL1100 - always immediately after start test mouse stops wo= rk, hot plug stop work (silently, without usb resets) - unusable here. 2. Renesas uPD720201 - works flawlessly here. 3. ASMedia ASM1042A - mouse/keyboard suddenly stops to work without any spe= cial load (silently, without usb resets) - completely unusable here. 4. VIA VL805 - mouse stuttering, keyboard skips pressing and sometimes repe= ats pressing till next press without any special load, under load completely unusable (silently, no usb resets). --=20 You may reply to this email to add a comment.
