I agree with Jay.... what is it you need to do? Downgrading the port doesn't seem to answer the original question?
If a device is only capable of 1.1, the port will figure this out and behave accordingly. If the connected device cannot communicate it's abilities I am not sure if it would work ( be recognized and initialize ) in the first place.
my problem is, that my usb->serial(COM) converter isn't working. My laptop sees it (it says hadrware working properly) and generates a COM port, but this port is not usable. I'm trying to program my pic(axe) with it and it says hardware not accessible. When i unplug the usb cable from my laptop and stick it in the PC i can download the program in my PIC with no problems. I think my PC is old enaugh to have USB 1.1 not 2.0 but laptop is pretty new.
i'm not familiar with picaxe but laptops are devices designed to live with limited power and usb ports are often starved (have limited power).
did you try to connect USB hub that has external power supply?
If the power is an issue, this should cover for it. some USB devices require use of two USB ports when connected to laptop (like USB<>IDE interfaces etc.).
thanks for the info.
those USB hubs are darn expencive can't I connect a battery to the wires to increase the power? of cource regulated power suply. Also my laptop is mainly on a cable so it should have the power needed. The picaxe only uses 2,3,5 pins on COM port (Tx,Rx,Gnd). I dont know if those need wery much power or not
And how big is the % that my thingy might start working after installing SP2? it takes a full day to get that on my computer and i don't have one to spear.
well, i'm soon done installing it and then tomorrow i test it and then when i get back to internet ( i go to a place where there isn't :cry: ) then i report if it worked or not.
well i changed the name. so the problem is that the signals from my usb->com converter are to weak for me to program my pic so i'm searching for an amplifier to get it operating. the schematic with a MAX232 was suposed to do so, but as it seems it can't right?
and now i'm seartching for a better amplifier circuit betwean com and my pic.
