How much Power can one USb handle ?? I have a Modem on one port i think, its using 500ma, its says USB root hub in the settings, Device manager. But i also have a printer connected their as well a 4ma printer, not sure if they are using the same power supply if so would it be ok to leave them like this, just installed them this way, becuase its the only way i can. I have an Addon card, which has twoother 100ma + devices on it as well. I have another USb connector on the board but can't get it to work sent a email to ASUS maybe they can help me getting it going. Thanks for any help. >> Stay informed about: How much Power can one USb handle ??

Would the 500 and 4ma be fine on the one port ? I might get a hub, if i can't get the other addon board to work, that will be all the USB ports i need and have one left over for something else.

500ma is the absolute maximum for some boards whilst 100ma is the max for others. but 504ma nay not be a problem. Usually add on boards are 100ma types I believe, unless they have a power socket added. Taff..........

The modem and printer are pluged into the MOBO USB 1_2, so i would think 500 ma would be for that. I did have my modem pluged into the addon card 500ma, so the card is 500 ma. But i could not plug anything else into it, even the printer, but on 1_2 the modem and printer work fine ?, no idea why that is. Got my USB stick and Steering wheel pluged into USB 4_5 thats off a card on the board. USB 2_3 i can't get to work not sure why, maybe it needs a jumper to power it up or somthing, maybe a dud card On Mon, 19 Jan 2004 01:35:38 +0000, taff <taff.TakeThisOut@the-valleys.com> wrote: >500ma is the absolute maximum for some boards whilst 100ma is the max >for others. but 504ma nay not be a problem. >Usually add on boards are 100ma types I believe, unless they have a >power socket added. > >Taff.......... > >On Mon, 19 Jan 2004 00:56:15 +1100, We Live For The One We Die For The >One <efternavn.TakeThisOut@doktor.dk> wrote: > >> >>Would the 500 and 4ma be fine on the one port ? >> >>I might get a hub, if i can't get the other addon board to work, that >>will be all the USB ports i need and have one left over for something >>else. >> >>Thanks. >> >> >>On Mon, 19 Jan 2004 01:25:51 +0000, taff <taff.TakeThisOut@the-valleys.com> wrote: >> >>>On Mon, 19 Jan 2004 00:42:58 +1100, We Live For The One We Die For The >>>One <efternavn.TakeThisOut@doktor.dk> wrote: >>> >>>> >>>> >>>>How much Power can one USb handle ?? >>>> >>>> >>>>I have a Modem on one port i think, its using 500ma, its says USB root >>>>hub in the settings, Device manager. >>>> >>>>But i also have a printer connected their as well a 4ma printer, not >>>>sure if they are using the same power supply if so would it be ok to >>>>leave them like this, just installed them this way, becuase its the >>>>only way i can. >>>> >>>>I have an Addon card, which has twoother 100ma + devices on it as >>>>well. >>>> >>>>I have another USb connector on the board but can't get it to work >>>>sent a email to ASUS maybe they can help me getting it going. >>>> >>>>Thanks for any help. >>> >>>Have a read of this article. >>>http://groups.yahoo.com/group/OziUsers-L/message/13380 >>> >>>A powered hub may be your answer. >>> >>>Taff........... >>> >>> >>> >>> <font color=brown> >>>www.sounds-pa.com \| <a style='text-decoration: underline;' href="http://www.thecomputerworkshop.com</font" target="_blank">www.thecomputerworkshop.com</font</a>> > > > > <font color=purple> >www.sounds-pa.com \| <a style='text-decoration: underline;' href="http://www.thecomputerworkshop.com</font" target="_blank">www.thecomputerworkshop.com</font</a>><!-- ~MESSAGE_AFTER~ --> >> Stay informed about: How much Power can one USb handle ??

I took a look at the USB 2.0 specification (http://www.usb.org/developers/docs) and section 7 states devices can consume 1-5 unit loads (1 unit load = 100mA); low-power is 1 unit load, high-power is more than 1. All devices start out in low-power and the device driver can enable high-power if needed. High-power ports must be able to provide up to 5 unit loads. Low-power ports need only supply 1 unit load. From this is sounds like you can have up to 5 devices on a single high-power port. However, if a device wants to operate in high-power mode (2-5 unit loads), you may not be able to attach other devices to that port. You would need a hub with external power. The device driver is required to not exceed available power. - Robert - "We Live For The One We Die For The One" <efternavn DeleteThis @doktor.dk> wrote in message news:ha3l00hf6oromd6l4f1rnd1fgjqk6at2ng@4ax.com... > > > How much Power can one USb handle ?? > > > I have a Modem on one port i think, its using 500ma, its says USB root > hub in the settings, Device manager. > > But i also have a printer connected their as well a 4ma printer, not > sure if they are using the same power supply if so would it be ok to > leave them like this, just installed them this way, becuase its the > only way i can. > > I have an Addon card, which has twoother 100ma + devices on it as > well. > > I have another USb connector on the board but can't get it to work > sent a email to ASUS maybe they can help me getting it going. > > Thanks for any help.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: How much Power can one USb handle ??

Asus has opted to include two onboard USB headers, however if you plan on using both headers, you will be forced to disable the use of the ACR slot, if you do in fact use it. This, along with the USB wake up setting can be adjusted via the jumper set right above the headers. Taff..........
