Why on earth did HTC not use USB 2.0?????

[jack_2231]

Ok, so I am pretty proud of myself, having solved the Iguidance AKU 3.5 problem. So naturally I am installing maps.

Only one thing. It is taking a couple of years. I think I will be renewing my sprint contract before this loads up the maps!

So I was wondering, do any of you know what is up with HTC not splurging extra $1 for a 7-year-old USB 2.0 chip on a $600 phone???? Is Activesync to blame? Is it actually USB 2.0 but limited by some strange quirk? What is the scoop?

I think it's more the case that the 6700 really can't go much faster then usb1.2 speeds.

Let's review.

802.11b max speed, 5.5mbps (each way)
6700 802.11b max speed, about 3mbps

USB 1.2 max speed 12mbps
6700 USB1.2 max speed... uh, about 3mbps

So sure, they coulda put usb2.0 in, but then people would *really* complain about the speeds.

It's weird tho, my good old $60 zen nano can cook along at 4-5MB/sec (40-50mbps) with USB2.0.

So I think it's got some serious bottlenecks elsewhere in the I/O subsystem.

Actually I believe it had to due with the fact that the Intel PXA270 didn't support USB v2.0 when the 6700's hardware was developed. I know the later generations supported USB v2.0, but I believe the first ones where only v1.1; hence why the main reason the 6700 wasn't 2.0.

FYI, the PXA270 also has USB host functionality built into it too, but few manufacturers chose to implement it. (industrial/enteprise devices and a handful of consumer PDA's (Loox T830, Asus A730, ....))

This is very insightful. I think anyone with Pocket Hack Master overclocking will know there are a dozen different things to tweak. My guess is that one of them drastically increases speed. CPU speed itself has little if any effect on the xfer rate. So the idea that it is cpu related tough to swallow. It is like they are using a 9600 serial port inside to xfer data from one side to the other of the main board. Microsoft was definitely in the "all you need is 640K" zone when designing this.

I didn't realize the USB speeds were lacking since my laptop has a card reader, and I have been using this registry edit to help:

802.11G
EDIT2: removing reg entry mix up as it is not only not on topic, but as Jack points out, not working.

HKLM\xxxxxxxxxx

Haven't checked my speeds yet 2 compare so try and see, it can't hurt.


EDIT1: Woops were talkin USB. not wireless lol, lacking some sleep.

I have also posted elsewhere that our 6700's can support higher Bus speeds(260 and higher) thru PHM, which makes More difference than just boosting CPU speed...

EDIT3: Sry 2 get slightly off topic, but as requested further down.
A good stable setting thru PHM that would work on newer 6700 units which dont overclock as good as older units is:
CPU:520, Bus260, Mem130, LCD65

I got bad news - even the 6800 coming out in a couple of months is still USB 1.1

Anything that HTC sells to Sprint or Verizon is rather antiquated.

HTC 6800 110 x 60 x 20
ETEN X800 113.5 x 60.5 x 15.8 - Much thinner - but no keyboard - I'd gladly give up for the thinner design - but they could keep the 6800 for people who want one. I would imagine Eten will also make one with a keyboard but I don't have any info about that unit.

HTC - 240 x 320
ETEN - 480 x 640 - 4 TIMES the resolution better for browsing, e-mail, documents, GPS etc.

HTC USB 1.1 - Maybe they are some sect of amish and can't go beyond 99 technology
ETEN USB 2.0 - they noticed USB 2.0 came out around the turn of the century and decided progress was good

HTC - No FM tuner
ETEN - FM

HTC - NO GpS
ETEN - GPS on board

Well if it's disinformation, then it DOES hurt since it wastes people's time.
According to this post, this hack doesn't work. Why not post xfer #s? Won't take that long. If you or anyone has specific PHM settings that are stable and have a big performance enghancement over XCPU and not in BigJ's rom, please post em.

LOL But seriously I don't think there are that many Amish in korea. I too get the idea that the USA (Sprint is just 1) is crippled when it comes to tech. Having GPS, Wireless G (?), and USB 2.0 intentionally switched off, artificially low bus rates, etc. Sprint/us phones suck. I am waiting for asia to take us completely over so the pain finally disappears.

I'm happy with Sprint's cell network and with the rate I get.

I hate pretty much everything else about Sprint. In 8 months, my contract should run out and then I'll probably switch to Cingular if they still let me use any phone on their network I want. I'll pay more for the service but at least I'll have a decent phone. When my time comes, I'll do some research and try to find a way to get employee referral rates from someone. In 8 months, the x800 is still going to be about 2 years ahead of anything on Sprint's network so that's the unit I'll be looking at getting.

Recently there has been a lot of posting about the crappy phone selection on Sprint's forum - buzz about wireless. I sincerely doubt that anything can be done about correcting the direction of that behemoth in time for me to get a new contract.

I blame the technologically backward phones we are offered in the US on Sprint and Verizon. If they said to HTC, we are only buying phones with USB 2.0 and VGA screens from this point forward, you can be sure HTC would be selling that unit to them. Sprint also takes so incredibly long to "test" a phone that they are obsolete even if they are cutting edge when they are delivered to Sprint. Sprint's "testing" includes turning the phone on and making a call. They don't test to see if PDA phones run apps well, that e-mail works, that they have enough memory, etc. Not sure how long it takes to see if you can make a call and receive a call.

I really really wish Sprint had an "open" network where you could put any phone you want as long as it had CDMA set for Sprint. You can be sure that reputable manufacturers like HTC, ETEN, Samsung etc would make sure it was compatable quickly so they could sell you more phones.
