My cellphone(LG G-1800)having 64MB USB flash drive and it is working well with my computer but it is not working with my PSR-3000 and whenever i connect my cellphone to the computer, the message "USB ON" appears on the cellphone screen that means the USB drive is working well and the same message is appearing on my cellphone when i connect to my PSR-3000 but the USB is not appearing on the PSR-3000 display,as i can see preset,user,card only.
So is there any solution for this problem?
