USB2 speed :(

[adamfilip]

I have a 1.6 Powermac G5
I use a sandisk 6 in 1 memory card reader. its a USB2 reader
I use some compact flash cards that I read and write from
on my G5 it runs at USb1 speeds

when i plug the reader into my dads pc laptop it screams at usb2 speeds

I am directly connecting the reader to the front port on my G5

Any suggestions?

[russed]

have you tried it on the back ports of your powermac? if so are there any differences in speed?

 

[Nickygoat]

Shouldn't be - according to this all the USB ports on the machine are USB2.0. I have to admit I thought the front one was 1.1. I know that doesn't help the OP who should try it anyway

 

[Sutekidane]

That's very strange. It could be the USB flash reader, but you should try using the back ports as mentioned above and see if it makes any difference.

What's the brand? Many USB storage devices are picky (some brands of Flash drives performed horribly on Macs in a recent review, for example, while others offered great performance [Sandisk's was one of the best, I think]).

its sandisk card reader
but the cards are various I have a lexmark, kingston. and some generic
also I have a sandisk 128mb Flash USb that is a usb2 card but it still runs usb1

I will try the rear ports and report my findings

 

[adamfilip]

well I tried it with the reader plugged directly in the back port

480Mb/sec is USB 2, why Fat16?
Does the camera recognize FAT32?

Transfer a big file on both systems and give us particulars.
If nobody can come up with a solution to your problem, it at least gives some hard evidence for people to look up later.

I dont know why Fat 16
its A Canon 10D D-SLR
it formats it that way

 

[Flying Llama]

What I would do...

Hmm... what I would do is back-up all important things on the card, reformat it, test the speeds. If they are faster, I would keep it that way unless the Canon doesn't recognize it, in which I would reformat it back.

 

[adamfilip]

I formated the card using disk utility on my g5
tried the standard hfs jounaled and several others. without any noticeable
speed differenc

The thing that you have to understand that you are doing much more than just transporting data. You are also reading, writing, and verifying data. Flash drives are not terribly fast. You also have to be very careful when comparing Windows speeds to Mac speeds. The data copy is complete only after the little LED on your flash drive stops flashing.
