about sl811hs
i have two SL811HS,one mark is\"cypress\" other is \"scanlogic\", and they are HW revision is rev 1.5. now,i use 8051 and write a program for SL811HS. the program running with \"scanlogic SL811hs\" can get USB device any data,but the program running with \"cypress SL811HS\" can\'t get USB device any data(usually get \"time out or NAK\"). same program of 8051, but use different SL811HS(cypress and scanlogic), get different result .>_< what this problem? thank you very much!
