mini USB speed - Touch CDMA Windows Mobile ROM Development

Hi all. Just got my Touch through Bell Canada a few days ago, and so far it's great. One minor gripe I have is the slow USB 1.1 speed through the miniUSB port. I'm using Softick's Card Export to avoid having to fiddle with the microSD card cover, but transfers take forever if I'm loading on a lot of mp3's.
I've noticed specs on the Touch Dual and Cruiser list the USB as 2.0. Is there any way to upgrade the usb drivers in the original Touch? Or is it a hardware limitation?
I'm plugging it into a Linux (Debian) system if that makes any difference. Thanks.

I believe the Touch and Mogul are USB 2.0

Are file transfers known to take longer when using Card Export as opposed to an actual card reader? Plugging the card into a reader gives normal transfer times, that's why I assumed the USB port on the Touch was to blame.

I am not sure. I know that it's faster doing it through my card reader on my laptop as well.
--James

After checking the transfer speed again, it does appear to be faster than USB 1.1, just not full 2.0 speeds. Looks like a limitation of the Card Export software itself.

USB Card Reader

Hi,
Is there any usb2 flash card reader out there that is fast?
I just bouth a sandisk MobileMate SD, a very convenient little thing, but it doesn't seem to be very fast, transferring 5b takes 30 sec roughly.
Are all readers the same, or can I buy someting with some performance?
I understand there is a limit to the SD card type you use, but c'mon, 200kb/s ???
I've got one of those 6-in-one FDD size USB2 ones in my machine, and it's pretty quick. I'd imagine most USB2 ones are going to be about the same speed. Sounds like you're getting low-speed USB rates of about 1.5Mb/s
is your USB port is ver 2
even your flash reader is ver 2
but your pc usb port is not
will not be fast
correct me if I m wrong

SD card reader?

Hey guys, is there an external card reader that would plug into the micro USB port on the captivate? I've been searching for a while but all I can find is micro SD to SD card adapters when I would like to import photos from a camera right into the phone
It would be a shame to have to just use micro SD cards to use the internal slot. Thanks!

I dont know of one that exists. But if youre trying to import your pictures you are going to be better off just inserting the micro sd into your phone and then copying all the image files to the phone. Its essentially the same process you would do if you had an external SD card reader except you actually have to put the SD card in the phone.
here u go.

I'm not sure that there is such a beast that would plug into the microUSB, and if there was, I'm not certain that the Captivate has the functionality/interface to read and copy from the microUSB Slot. I'm pretty sure you need the computer as a go-between if the microSD isn't in the phone itself.
I think your best bet is directly putting the microSD from the Camera into the Cappy or you'll have to upload them to the computer first, then to the phone. Sorry
I've always wanted something like that, its a great idea but such a thing doesn't exist. Closest thing would be to get the flash drive adapter with the microSD slot built in.

Yeah, that's not really possible. For one thing it's a jack, not a plug. For another, it would need to power the device attached to it while still being able to be powered from the same port for charging. For another, it would need to be able to configure as a device or a host which would really be hard. And another, it would need to have drivers for SD readers, FAT, NTFS, and all kinds of other things.
this would probably be you best bet

Wow. I stand corrected. That's a really flexible controller chip. They should have shown a backup battery being used as well in the pics too.
a kernel with USB HOST mode,
a USB OTG cable
a USB to micro USB cable
a USB card reader
a SD to microSD adapter.
and you can do exactly what you want....
but you will need a back pack to carry all your cables and adapters.
One step could be saved with this

But nobody sells it, and who wants to splice USB cables?

How about this?

This part is odd:
- With own browser and ES browser
- File system format: FAT32 (does not support NTFS)
in general for any phone or tablet
an external hardrive like 1 or 1.5TB with USB will be a dream, u can power the drive with extra USB. But what about powering device with the screen? I think it will run out of juice much faster in this kind of setup. Your thoughts?
From the research I have done, it requires an org cable, an USB y-cable for hooking up an external power, and a from with org support. The two cables can be found on Amazon for 2-5$. You could use any USB charger or for portability... get one of the battery packs with USB output. Portable, but it is a lot to carry around.
You can also use a powered USB hub in place of the y cable.

USB copy speed is extremely slow

USB copy speed I'm getting is max 3.2mb/s, and goes as low as 1.5, is this normal? I imagine I should be getting a lot better speeds over USB 2.0 and my SD card is a new Sandisk class 6 micro sd card.

Use the mirco SD adapter provided with Ur purchase of mirco SD card.. wire is just slow... adapter have direct contact with the hard drive.. so u would get faster transfer rate

I'm getting 8-9mb/s reading from sd to hard drive, writing from hd to sd is much slower at 2.5 - 3mb/s. This is using the original HTC usb cable.
Mmm try with wifi, there are some usuful app for this
USB is a mystic hardware somethimes have mysterious problem :s
inviato da HTC Desire Z
I have slow speed with usb too but only with Windows. If i use linux i get extreme speed over 15 Mb/s. I don't know if Windows has any restrictions...
Yeah I would just try either Bluetooth, a microsd adapter, or Wi-Fi instead.
Adapter is usually the fastest as the reader can interface almost directly with the hardware. Over USB you have several factors to consider, the speed of the port, as well as the speed of the phone (i.e.: what Mhz is it running at... and is the phone busy with something), and the speed of the internal microSD reader and so forth.
Plugging the card into the reader would be the fastest, however not very useful if you gota turn off your phone just to get the card out.
I've never tried the Wifi app route as for me the USB route has been fast enough, but can take a couple minutes to transfer say my CWM backups from the card to the computer.

USB OTG - lackluster speeds?

I want to use my Mi Mix 2 (MIUI 9.6.1.0 Global) with a hub to transfer files (pictures) between two external storages. The transfer rates are ok-ish, but I was hoping for more. Maybe someone here knows if it can be sped up?
I want to be able to back up pictures from a SDXC card (SanDisk Extreme Pro U3 128GB) to an SSD (Crucial BX300 480GB) in the field, using my phone to move the files. The hub I got is this one: click here, and even though it's a rather cheap construction it works as advertised.
When I connect the hub to my PC (USB Type C 3.1) I get cross transfer speeds of around 85 MB/s, which is pretty much the maximum read speed of the SD card.
Connected to the Mix 2 (USB Type C 2.0) the set up only averages around 14 MB/s, which isn't bad, but less then I expected, since USB 2.0 should have transfer speeds of up to 35 MB/s. The Problem is, that moving 128 GB at that speed takes 2.5 hours, which a) is too long, and b) is super hard on the Mix 2's battery, which probably wouldn't even hold that long.
Now my first question is: Why oh why does this otherwise wonderful 2017 flagship device only have USB 2.0?!
And the second one is: Who knows a solution other than buying a Samsung with USB 3.1?

Power pass thru with a Seagate Slim.

Hi all,
So, I just picked up a Samsung Tab S4, near new (in box), at my local pawn shop for $280.
It had no sign of ever having been used, smokin' deal, eh?
Quite the upgrade from my Fire 10, no?
I also found a likewise near new (in box), still wrapped in plastic, Seagate Slim (2 TB) for $20.
On a roll, right?
So, I've come here to ask...
1)Is it possible to view video directly off the hd?
2)If so, what power pass thru cable or dongle has anyone found to work well?
3)Lastly, for power I would like to be portable, so would a standard brick work or do I need a PD or IQ specific type?
I see there are plenty of dongles out there ranging from $15 - $75...any suggestions?
Simplest setup would work for me, especially if there was a cable alone I could use, I don't need a ton of ports.
Thanks, really!

So the short answer is yes you can play videos. The long answer is that your drive is likely formatted NTFS and while there are work around and apps that will let you utilize drives formatted as NTFS, I've found it just isn't reliable, convenient or consistent using an NTFS drive. Mine is a 1 TB drive. The problem with Fat32 is that there are partition size restrictions and file size restrictions - there are supposedly work arounds for the partition size limits, but files can't be bigger than 4GB. And some video files, particularly iso's, are bigger than 4GB. I think you are better off buying a 512gb or 1tb micro sd card and storing the video locally.
There are multiple threads discussing power formats and powered usb hubs. Mostly the hube will have full size usb 3.0 ports.
Power is complicated. Samsung does not use / is not compatible with PD or iq, and is not fully compatible with QC. They use a modified version of QC 2.0.

This is a few months old, but I thought I would revisit my reply. I may have been too quickly dismissive of the external hard drive idea.
I have a 1TB external USB 3.1 drive. It was formatted NTFS, and did Not play well with Android, even using Paragon's NTFS for Android. As I pointed out, exFat is restricted to 4GB max file size, and I had some ISO disk images on my drive. I had a total of about 600GB on the drive, about half video back up, the other half split between music library backup, twentyish years of digital images, and twentyish years of desktop document backups. The data I use most is my 3000+ book Calibre library. I also had two full size internal hard drives that I had pulled from my last desktop (and never replaced), along with a SATA1 to USB 3.0 powered adaptor.
So I backed up the video to one of the 500GB drives, the rest to the other, and reformatted the 1TB drive as exFat32. Then I copied the video excluding the few large ISO images along with "the rest" back to the reformatted 1TB drive. I was surprised there weren't any other files > 4GB.
I have two cables for the 1TB hard drive -- it has a wide bladed "micro B" port that carries power and data simultaneously. I have a USB 3.0 to micro B, and a USB C to micro B. So it works well, with both cables. With a hub, I can plug power + USB 3.0 hard drive cable to the tablet. With the USB C cable I can directly connect the hard drive to the tablet, and have experienced no problems with power delivery -- drive works fine, no stutters, but I don't know how fast the drain on the battery is. Certianly, you can copy files back and forth without issue. Browsing with Solid Explorer works well.
I still think you are better served with internal micro SD memory. I recently upgraded my 400GB micro SD card to a faster, 512GB PNY card for $90.
Many USB C hubs also have a micro SD card slot, so you can turn the hubs directly into a solid state hard drive with a cheap micro SD card -- if you have an old card, like I have the 400GB card I pulled, or you can buy a newer 256GB card for under $50. I have to imagine the power draw is much less, and the form factor is greatly superior -- my USB C Hub is ~ 40% smaller in volume, and is only 40gm versus 170gm for the hard drive (that is, a little under 2oz, and the hard drive is a little over 6oz). The micro SD card slot on the hub is spring loaded, and when it is loaded, the front of the card is virtually flush with the front of the hub. And it is easy to pop it into and SD card adaptor to put into a laptop.
Take care,
Joe
