I need more than 2 USB ports.

The USB splitters that are 3.0 seem to mostly be the plug in type -- not convenient. is there a reason the hubs need to be powered? Is there a splitter I can use safely? thanks. Just got a new macbook pro 13. Thanks.

Using more than one USB Port at a time?

So, I'm trying to record something in a project using my Rocksmith USB to 1/4 inch cable, but I also need to make a screen recording of me doing that for a school project using my RockBand USB mic. The problem for me is that only one USB Port recognizes these two, and the three that don't aren't dead, as they work with everything else I have. How do I set it so that more than one USB port can recognize these devices? I don't want to have to keep switching every time.

Thanks mhartnett.
I have looked at the example on the link you gave. According
to the example for the FileReferenceList in the documentation, it
seems to make multiple or rather separated requests to the
server-side upload script.
So for example if I have 3 files to upload, the script will
call the the upload() function of the FileReference class thrice
with the URLRequest(which is the server-side upload script). So in
this case, my server-side script that is handling the upload will
only upload one file at one time.
Is there a way where I can have say all the 3 files sent
together to the server-side script, and then have them uploaded all
at once within the server-side script itself?
So say my PHP file, I could have access to like
$_FILES['Filedata1'], $_FILES['Filedata2'] and $_FILES['Filedata3']
together at one request.

Application by using more than 65535 UDP ports

Hello all!
I'm now implementing a device simulator in VC++ to performance a load test to our server application. I need to simulate a huge number of devices to communicate with this server via UDP, each device shall have its own UDP port exclusive during the
simulation.
Since there are maximal 65536 ports pro IP address and from 0 to 1024 are reserved by OS, theoretically I have 64511 free ports for my Simulator application, considering some ports are required by some services/applications, the free port number may a little
fewer, I'm assuming this number is 60000. According to our software requirement, I can't reach the required simulating device amount under this port limitation.
If I'm right, if one computer has more IPs, I shall have more than 60000 free ports. My simulator runs under Windows Server 2008, 2 physical network adapters and I used following command to change the dynamic UDP port range to get 60000 UDP ports:
      netsh interface ipv4 set dynamicportrange protocol=udp startport=3000 numberofports=60000
My questions are:
1. Is this setting globally available or for each IP address?
   I tried to set the parameter "numberofports" to 120000 but it didn't work.
2. Shall I set for each IP address separately a UDP port range?
3. If this setting is for each IP addres available, I have following problem:
   For two IP address, I could bind 60000 ports in total to 60000 UDP sockets, e.g IP1 20000 ports and IP2 40000 ports, or IP1 40000 ports and IP2 20000 ports. That means I can still use maximal 60000 UDP ports.
Unfortunately, I can't find any reference about this topic in Internet, does anyone have my similar situation?
Thank you in advance to teach me a solution!

" I need so many UDP ports because our product has "state", and our Server application maintains connection sessions for each connected device."
Couldn't you add some information to the datagrams that identify the state? That may require less resources than creating a zillion of sockets. Though I suppose that using a single socket would lead to serialization and that will hurt scaling...
"How much memory does one socket need? I didn't think about this topic....."
Hmm, memory is need for the socket data structures and buffers. Probably a few kilobytes. Let's do a test and see what happens:
#include <winsock2.h>
#include <cstdio>
#pragma comment(lib, "ws2_32.lib")
DWORD WINAPI ServerThread(LPVOID addr) {
SOCKET sk = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
if (sk == INVALID_SOCKET) {
printf("socket failed\n");
return 1;
int err = bind(sk, static_cast<sockaddr *>(addr), sizeof(sockaddr_in));
if (err != 0) {
printf("bind failed\n");
return 1;
char buffer[256];
sockaddr_in from;
int fromLen = sizeof(from);
for (;;) {
int length = recvfrom(sk, buffer, 256, 0, reinterpret_cast<sockaddr *>(&from), &fromLen);
printf("got %d bytes from %s:%d\n", length, inet_ntoa(from.sin_addr), htons(from.sin_port));
int main() {
WSADATA wsaData;
int err = WSAStartup(MAKEWORD(2, 2), &wsaData);
sockaddr_in to;
to.sin_family = AF_INET;
to.sin_port = htons(4242);
to.sin_addr.S_un.S_addr = inet_addr("192.168.1.68");
CreateThread(nullptr, 0, ServerThread, &to, 0, nullptr);
const char *addrs[] { "192.168.1.40", "192.168.1.41", "192.168.1.42", "192.168.1.43" };
SOCKET sockets[_countof(addrs)][30000];
sockaddr_in from;
from.sin_family = AF_INET;
int count = 0;
for (int i = 0; i < _countof(addrs); i++) {
from.sin_addr.S_un.S_addr = inet_addr(addrs[i]);
for (int j = 0; j < _countof(sockets[i]); j++) {
SOCKET sk = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
from.sin_port = htons(65535 - j);
err = bind(sk, reinterpret_cast<sockaddr *>(&from), sizeof(from));
if (err != 0) {
printf("bind failed while creating socket %d on %s:%d\n", count, addrs[i], 65535 - j);
closesocket(sk);
sk = INVALID_SOCKET;
else {
count++;
sockets[i][j] = sk;
printf("created %d sockets\n", count);
char buffer[256];
for (int i = 0; i < _countof(sockets); i++) {
for (int j = 0; j < _countof(sockets[i]); j++) {
if (sockets[i][j] != INVALID_SOCKET)
err = sendto(sockets[i][j], buffer, 256, 0, reinterpret_cast<sockaddr *>(&to), sizeof(to));
This creates almost 120000 sockets on my machine (Win 8.1). All the 192.168.1.x addresses are on the same network adapter, 4 of them are used for "clients" and 1 for the "server". Clients have ports in the range 35535 - 65535 so you get
around 30000 sockets per address (a few ports are in use so you won't get exactly 30000 unless you adjust the code).
When the program starts the kernel non paged pool jumps from ~50MB to ~200MB. That means around 1.3KBytes per socket.

How can I get more than one firewre port ?

Hello,
how can I get more than one firewire port ? I'd like to be able to connect my canon HV30 camera as well as my firewire external HD at the same time so I can use firewire to upload the videos I've taken. Is this possible?
TIA

Hi ginestre-
Many FireWire hard drives have 2 firewire ports so that you can daisy-chain devices and connect the camera that way.
Daisy-chaining is not the most reliable method, but it works, so you could buy a FireWire hub.

PS CC Says I need more than 512 Vram ...

I was using Photoshop last night just to prep a couple of photos for class submission (3 pictures, just reducing their size for web consumption), and I got the message stating that I needed more than 512 Megs of Vram, which was odd to me, as I have 1024 Dedicated available on my video card. I don't run a dual monitor setup any longer, but I do have an ASUS PBs278 that's running at 2560 X 1440. My current graphics card is an ATI Radeon 6800 HD, and my windows 7 system is running on 8 gigs of ram. Up till within the last week, CC has worked just fine, but the other day on boot, it took an unusually long time to get into the software. It eventually did, and I'm wondering if that was an update or some such that's now made the software decree that if it doesn't have the 512 it thinks it should have, the 3d functions won't happen. I don't know if it's a consequence of the larger quantity of pixels being pushed, or if it's the video card getting too old to support CC at such a high resolution now, but some help would be amazing.

Windows 7, 64 bit. I haven't been able to replicate the error, but I have the new drivers as well. I hope this just ends up being a fluke.

How, using Adobe Connect can increase the number of participants in the meeting? I need more than 25 people.

Hi, I use licensed Adobe Connect. Earlier in the meeting could involve up to 100 people. Now only 25. How, using Adobe Connect can increase the number of participants in the meeting? I need more than 25 people.
Thanks for your help.

The purchasing option through adobe.com only allows up to 25 attendees. If you need more than that, you will need to purchase through a reseller. You can find one that is able to sell in your part of the world, here: Adobe Connect Partners. Just reach out to one of the Global Partners.

I need more than the maximum allowed 30 profiles - how do I change this?

I need more than the maximum allowed 30 profiles - how do I change this? Once I reach 30 profiles and I try to add one - it just deletes one automatically thus only allowing a maximum of 30. Please help.

You are talking about 30 Firefox Profiles on the same Windows Logon User Account?
I never saw that as a limit myself. I had 53 Profiles at one time, although I haven't done that since Firefox 3.0. It was causing an extended launch time and I started using "remote" Profiles that weren't controlled by the Profile Manager and weren't in the '''profiles.ini''' file; launched by command line. Like this in the Target line for the desktop shortcut: <br />
''' "C:\Program Files\Firefox_4.0_zip\firefox.exe" -Profile D:\Mozilla\Active-Profiles\4.0_10-15-10-N '''

NEED more than 15 menu item in Context Menu ????

Hi,
I really need to have more than 15 menu item displayed on Context Menu. I desperately need some workaround or ideas to achieve this
My client has invested thousands of dollar in Flex Project, he definitely need more than 15 menu item.If this project failed , client will NEVER think to invest in flex.
Had I been aware of this limitation before I would have thought some solution by now.This comes as a surprise to me at the last moment ,just fews days before Prod Date.
I cant also user java Scrip heck as my Flex application is running inside Dot net Container , I do not access to the luxury of java script
Pls gents help me get rid of this ...PLEASE provide some ideas.
Thanks in advance.
Thanks,
Dharmendra

Thanks Natasha,
I got your point but as for as I know grouping like Quality is not possibel in Flax Context menu. I also cant go for window style menu(file,edit) because I need them to be displyed on DataGrid right clk . I am designing a trade datagrid where in trader can see all trades and he can approve/reject etc by just right clk and selcting proper menu item form Context Menu.
In case of window style (acrobat.com) menu trader will have to reach to menu instead of getting all options on mouse right clk
I will have to think other alternative wich provides same ease as cotext menu.(God knows what is that )
Once again thanks for suggestion.
Regards,
Dharmendra

Need more than 90 minutes of continual video

,Need more than 90 minutes of continual video? Hi all,
I'm using the Vado HD [first gen] as a "hidden cam" type of thing for a play that I am filming. I have 2 normal cameras set out in the audience, but I want to mount the Vado HD above the stage for a bird's eye view of a sword fight scene that I can cut to when editing footage. The problem is that the fight scene happens near the end of the play and there are no intermissions.
Since the filesystem used on the Vado HD is FAT and not NTFS or HFS+, I run into the 4GB limit and the camera simply puts itself to sleep about 45 minutes into recording even though there is more space on the dri've and the battery is fine.
Can I reformat the Vado HD with HFS+ or NTFS? [i use a Mac but can run windows via VMware Fusion if need be]. Is there any way to squeeze 90 minutes of video in one file on this camera? If I reformat the camera, will it mess it up? [i don't use any of the apps that were installed on the camera - i moved them from the vid camera to my laptop actually, so i don't care about losing anything valuable on the vid camera].
Thanks for any tips you might have!
/vjl/

Could the reason be that you are capturing to an FAT32 format hard drive and it is only allowing you a limited maximum file size? Not sure but I think it is 4GB which would equate to 1/3 of a DV 13GB hour ...or about 20 minutes.
If that is correct, and you should be able to tell because the capture window will display the file size limit as space available during capture, you could do one of two things:
* reformat the drive as NTFS which removes the file size limitation (I have just done this on an external drive for exactly the same reason), but do look up online instructions for this and do it carefully.
* if the material is not long continuous shots of over 20 minutes, switch on Scene Detect during capture; it's wise to cut material up into smaller chunks in any case as huge files become very unwieldy and handling them could slow your machine right down.

Thought you could use this info about getting FireWire to work! First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 15 minutes. plug it back in and try FW.
If that didn't work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
If that still didn't get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
A bad internal PRAM battery can also cause FireWire to not be recognized, so make sure it's good! Also, here is Apple doc.#88338 on getting FireWire to work.
Here's another Fw Faq.

Why do we need more than one retained earnings accounts & what is the use?

Hi FI Experts,
Why do we need more than one retained earnings accounts, what is the precise use of two?
I know the retained earnings account is used to carry forward the balances during the year end to the balance sheet and there by making the p&L A/cs balances as zero.
I guess the second one is used for different valueations for example as depreciation accounts for different valuations will have different retained earnings accounts.
Kindly correct me if I am wrong and eloborate on the use having more than one retained earnings accounts.
with regards
Ramesh Y

Hi,
Well, separate retained earnings accounts are used for parallel financial reporting, it means when you need to report in accordance with, for example, local GAAP and IFRS or US GAAP at the same time. Several retained earnings accounts are necessary when the company chooses account based approach for parallel reporting. (GL accounts are broken down into several groups, for example you use different accounts for IFRS valuation, for local GAAP and they are also shared accounts common for both principles.)

Business graphics need more than one category

Dear All,
     We have a issue for business graphics need more than one category about web dynpro abap.
   Our data:
   plant   month   qty
1000   201101 10
1000   201102 30
2000   201101 30
2000 201103   40
Now we need one category for "plant" and other category for "month", Data is qty.

Hello Bill,
could you explain bit more about your requirement? How would you like the graph to be renderded with two categories. Can't you club Plant and Month into one single category (1000-201101) and display it?
BR, Saravanan

Firefox is the only browser that need more than 700 ms accesstime, when others need only 10! Why is that???

I have tested Google Chrome, Firefox and Internet Explorer. Firefox is using between 500-1100 ms accesstime, using Bredbandskollen.se, while the other two only uses around 10 ms!

First of all, thank you for your response.
Below you can find the answers to your questions:
1) YES, I am using version 4, build 0024.00. Forgot to mention that I use Windows 7 64-bit and Firefox 11 (I don't use Chrome or IE)
2) I cannot confirm that, because the problem doesn't appear every time. For example, today EVERYTHING works OK! I haven't change anything or done something different, but since I boot my T410s, every site log in with ONLY one swipe (today even Yahoo for the first time). As I said, SOMETIMES PWM asks for one swipe, other for 2 and rarely for 3 swipes. But I think that when the problem appears, PWM need more than one fingerprint swipe every time I go to the website.
3) The setting for "before logging me into a Web site or application..." is "Every time". As I said, I need this setting to be "Every time", as my notebook sometimes is being used by other persons.
It is really a stange problem and when it appears it is very annoying. Have you any other ideas about what it's going on?
